Chapter 17.1, Problem 2RQ

Interpretation Introduction

Interpretation:

The catalyst speeds up a chemical reaction; the reason behind this fact needs to be explained.

Concept introduction:

Catalyst is used in the reaction to increase the rate of reaction.

Answer to Problem 2RQ

When the catalyst is added to a reaction then it changes the reaction rate, because it decreases the activation energy or changes the mechanism of the reaction.

Explanation of Solution

A catalyst is to increase the reaction rate of a chemical reaction by decreasing the activation energy. It decreases the activation energy so that more reactants react with a sufficient amount of increase to overcome the lesser energy barrier.

Conclusion

By adding the catalyst in the reaction, increases the rate of reaction by decrease the activation energy.
