Lesson Plan: Effects of Temperature and Concentration on Rates of Reactions Science • Third Year of Preparatory School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe and explain the effect temperature and concentration have on the rate of chemical reactions.
Objectives
Students will be able to
- explain how higher temperatures increase the rate of reaction by increasing the number of collisions between molecules,
- describe an experiment using different temperatures of water and effervescent tablets to illustrate the effect of temperature on the rate of reaction,
- explain how higher concentrations increase the rate of reaction by increasing the number of collisions between molecules,
- describe the experiment of burning iron wool in air and in a gas jar of pure oxygen to illustrate the effect of concentration on the rate of reaction,
- describe an experiment of reacting magnesium with different concentrations of hydrochloric acid to illustrate the effect of concentration on the rate of reaction,
- explain experimental observations in terms of the effect of temperature or concentration on the rate of reaction.
Prerequisites
Students should already be familiar with
- the definition of rates of chemical reactions.
Exclusions
Students will not cover
- catalysts,
- the effect of surface area and the nature of reactants.
