Chapter 17, Problem 57A

Interpretation Introduction

Interpretation:

The effect of increase in temperature on speed of a reaction has to be identified.

Concept Introduction:

Rate of reaction:

It is the speed at which a chemical reaction takes place. For higher speed of reaction, the reaction rate is higher, that means the molecules are combining with higher speed.

Answer to Problem 57A

Increasing the temperature, favours an increase in the rate of reaction, because by increasing temperature, the number of molecules increases with energy higher or equal to an activation energy.

Explanation of Solution

Effect of temperature on rate of reaction:

For a chemical reaction to takes place, there should be collisions among particles, the reaction will only take place if particles undergo collisions with minimum energy to make the reaction happens. That minimum energy is called activation energy. And to increase the speed of the reaction, the number of particles having energy equal to or greater than activation energy must be increases, that the temperature does. by increasing temperature, the number of molecules increases with energy higher or equal to an activation energy that increases the rate of a reaction
