Chapter 22, Problem 97A

(a)

Interpretation Introduction

Interpretation: To tell the effect of particle size on the chemical reaction.

Concept Introduction: For different chemical reactions, the rate of reaction is different. Some work at a slow speed while some occur fast.

Answer to Problem 97A

The size of the particle affects a chemical reaction. The particles with smaller sizes will have a higher rate of reaction as they have more surface area and vice-versa.

Explanation of Solution

The rate of a chemical reaction depends upon many factors which are as follows:

• Temperature
• Particle size
• Concentration
• Catalyst

The size of the particle affects a chemical reaction. The particles with smaller sizes will have a higher rate of reaction as they have more surface area and vice-versa or the rate of reaction increases when the particles are smaller in size.

(b)

Interpretation Introduction

Interpretation: To tell the effect of temperature on the chemical reaction.

Concept Introduction: For different chemical reactions, the rate of reaction is different. Some work at a slow speed while some occur fast.

Answer to Problem 97A

The temperature has a direct dependence on the chemical reaction. On speeding up the temperature the rate of reaction also increases.

Explanation of Solution

The rate of a chemical reaction depends upon many factors which are as follows:

• Temperature
• Particle size
• Concentration
• Catalyst

The temperature has a direct dependence on the chemical reaction. On speeding up the temperature the rate of reaction also increases.
