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.
Students 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. Students use retest methods to determine how using various amounts of initial reactants changes the reaction rate.
Students identify the factors that affect reaction rates. In this chemistry lesson, students design a lab to test each factors identified. They create a Power Point presentation and share their findings in class.
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.
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.
Students discuss the role of temperature in a person's reaction time and learn what a reaction rate is. They participate in an experiment in which reaction rates are recorded and discussed.
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.
In this reaction rates worksheet, students solve twenty problems including calculating reaction orders, reaction rates and writing rate expression for given multi-step reactions.
In this instantaneous reaction rate learning exercise, 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.
In this equilibrium worksheet, students solve 8 problems to find the equilibrium constants and reaction rates of given equations.
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.
Students listen to a lecture on the collision theory. They discuss the reactant and product changes during a chemical reaction. Students are taught the factors affecting reaction rates. They complete a lab on entropy, heat and free energy.
Mr. Mole and Mr. Matchmaker entertain and educate your chemists about how quickly or slowly reactants are used up in a chemical reaction. Thorough explanations of the influencing factors are offered, and demonstrations are done. After viewing the 18-minute video, learners complete a fill-in-the-blank and short answer worksheet to reinforce learning. You will appreciate having this high-quality resource to support your unit on reaction rates.
Engage your physical science class with an exciting investigation on the rate of reactions! Introducing molecular motion, energy changes, and the breaking or forming of chemical bonds. Explain that temperature, surface area, concentration, and catalysts affect reaction rates. Finally, reinforce the concepts by having small groups test one of the factors on the effervescence of antacid tablets and the combination of vinegar with baking soda. This is a comprehensive and well-written resource.
In this kinetics worksheet, students answer a variety of questions. They find reaction rates, determine the order of reactions and they determine rate constants. They calculate the half-life for reactants and they answer questions about rate laws.
Challenge your chemistry class with these complicated problems about reaction speeds, rate expressions, and limiting factors. Some space is available on this sheet for work. Additionally, the worksheet could be used as a whole-class practice through the steps needed for completion.
In this kinetics instructional activity, students solve seven problems related to chemical reactions and their rates. Students identify rate laws for mechanisms, they draw reaction diagrams, and they determine rate constants.
In this kinetics worksheet, students complete 7 short answers and problem solving questions on rate law, equilibrium concentration and factors affecting reaction rates.
A variety of questions that will ask learners to demonstrate understanding by showing calculations and the answers to questions about reaction rates. Some equations with concentrations are given where the moles and balance of the equation are requested. Some of the questions ask about the effect of a catalyst and multiple questions ask about rate determining steps.
This is an advanced rates of reactions activity. High schoolers will be determining reaction times, molarities, and reactions rates for different reactions.
