Reaction Rates and Catalysts in Ethanol Production
Here is a five-day module in which high school chemists determine what other materials can serve as catalysts for producing ethanol. Another objective of the lessons is to introduce reaction rate and activation energy. Learners also use a computer to analyze and present their data.
Reaction Rates and Equilibrium
Students examine the factors affecting reaction rates. In this chemistry lesson, students compare and contrast exothermic and endothermic reactions. They write equilibrium expressions using Le Chatelier's principle.
Concentration and Reaction Rates
Learners investigate how varying the concentrations, volumes, and other factors affects reaction rates. Students design and conduct investigations to obtain data used to create graphs of an uncatalyzed reaction vs. a catalyzed reaction. Learners use retest methods to determine how using various amounts of initial reactants changes the reaction rate.
Factors Affecting Reaction Rates
Students identify the factors that affect reaction rates. In this chemistry instructional activity, students design a lab to test each factors identified. They create a Power Point presentation and share their findings in class.
Rate Law Problems
If you need a variety of questions for reactions and rate calculations, this resource is for you. Inspire your students to manipulate values and equations to fit the questions. The word problems are quite involved and require young chemists to write the rate expressions, as well as to explain changes to reaction rates with different concentrations.
Rates of Chemical Reactions-The Iodine Clock Reaction
Students investigate the reaction rate of iodine and soluble starch. In this rates of chemical reactions lesson plan, students study the effects of varying concentrations of reactants and varying temperatures of reactants on the reaction rate of iodine and soluble starch. Students plot their data on a graph and interpret their results.
Kinetics Review Sheet
In this kinetics activity, students define 7 terms related to the energy of reactions, they find the average reaction rate in a reaction, they sketch an energy diagram for an endothermic reaction and they compare exothermic and endothermic reactions. Students find rate laws, reaction orders, rate constants and instantaneous reaction rates.
Antacid Tablet Race
Students compare the reaction rates of effervescent antacid tablets under different conditions. They investigate methods of increasing the power of rocket fuels by manipulating surface area and temperature.
A Plop and Fizz
Seventh graders perform an experiment to determine the effect of temperature on reaction rates. In this chemistry lesson, 7th graders take measurements and record data. They create a graph and analyze results.
Physical and Chemical Reactions - Factors Which Affect Reaction Rate
A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the conventional step-by-step manner. A worksheet is provided with questions to help learners process their observations. Although this was written for a high school chemistry course, it seems more appropriate for middle schoolers.
In this chemical reactions worksheet, students determine the reaction rate for various reactions, write balanced equations, create graphs showing the reaction over time, and calculate the activation energy and potential energy. This worksheet has 1 graph, 5 fill in the blank, 2 short answer, and 20 problems to solve.
What Influences Reaction Rate?
Middle schoolers study reaction rates, what determines how fast a reaction happens and how the chemical changes occur. In this reactions lesson students complete a lab where they use Alka-Seltzer to observe reaction rate and create a graph with their data.
Factors that Affect Reaction Rates
Collaborating chemistry pupils observe that temperatrue increases the movement of dye throughout water, stirring increases the dissolving rate of sugar cubes, and concentration of solutions increases the chemical reaction rates. These and other included activities are meant to contribute to understanding what affects the rate of reaction.
CH 302 Spring 2008 Worksheet 13-Reaction Rates
In this reaction rates worksheet, students solve twenty problems including calculating reaction orders, reaction rates and writing rate expression for given multi-step reactions.
Antacid Tablet Race
Students complete experiments to determine how rocket fuel is affected by surface area and temperature. They compare the reaction rates of antacid tablets. They discuss their results to complete the lesson.
Instantaneous Reaction Rate
In this instantaneous reaction rate worksheet, students draw an energy diagram for a given reaction, they determine the rate law for a reaction, they determine a rate constant for a reaction and they determine the reaction rate for a reaction.
Measuring Reaction Rates
In this chemical reaction worksheet, students determine the rate of consumption or rate of production for given reactions. This worksheet has 14 problems to solve.
In this chemical reactions worksheet, pupils explain why certain reactions take place slowly or quickly. Students calculate the rate of consumption for given reactions. This worksheet has 14 problems to solve.
Reaction Rates and Catalysis in Ethanol Production
Students investigate alternative catalysts for the degradation of hydrogen peroxide. In this fermentation lesson students complete an activity that breaks down cellulose into sugar.
Factors Affecting Reaction Rate
Students study the collision theory and explain how the rate of a chemical reaction is influenced by the reaction conditions. In this reactions lesson students divide into groups, discuss the factors that influence reaction rate and define a catalyst.
