Lesson: Effects of Temperature and Concentration on Rates of Reactions Science • Third Year of Preparatory School

Join Nagwa Classes

Attend live Science sessions on Nagwa Classes to learn more about this topic from an expert teacher!

In this lesson, we will learn how to describe and explain the effect temperature and concentration have on the rate of chemical reactions.

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.
