Chapter 20, Problem 89A

Interpretation Introduction

Interpretation:

five factors affecting the rate of reaction are to be mentioned.

Concept introduction:

The rate of a reaction can be affected by different physical and chemical factors.

Answer to Problem 89A

The factors that affect the rate of reaction are:

• Presence of a catalyst
• Presence of chemical inhibitors
• Physical conditions like temperature and pressure
• Concentration of reactants
• Physical state of the reactants.

Explanation of Solution

• The presence of a catalyst increases the rate of reaction.
• The presence of an inhibitor reduces the rate of reaction.
• Physical conditions can alter reaction rate depending on its type.
• In a simple reaction higher concentration or reactants increases the rate of reaction.
• Powdered or fluid reactants interact better and have higher reaction rate.

Conclusion

The above listed factors can affect the rate of reaction.
