Effect of Concentration of the Reactants

How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

If your pupils think a catalyst is a list of their cats, then this might be the lesson for you! Young chemists study the effect of temperature, catalysts, concentration, and particle size on reaction rates during four different...

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...

In this rate of chemical reactions worksheet, learners experiment with different concentrations and volumes of hydrochloric acid mixed with magnesium to explore the rate of chemical reactions. They measure the rates of the reactions and...

Young scholars 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...

High schoolers 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...

Students create predictions on what they believe happen to reaction rates when temperature is raised. They use hot, cold, and room temperature water for this experiment and observe the differences. They graph their observations and...

Do animals breathe faster when given more oxygen or more carbon dioxide? Young scientists observe the respiration rates of locusts under a variety of gas concentrations to answer that very question. They collect data, analyze the...

High schoolers complete an experiment with Alka-Seltzer and reaction rates. They control the rate in which gases are allowed to escape. They test their predictions and observe what happens during the experiment.

Students observe demonstrations to show factors that affect rates of chemical reactions. In this rates of chemical reactions lesson, students investigate how catalysts, reactant concentrations, temperature and surface area affect the...
