Chapter 13.1, Problem 1PP

Interpretation Introduction

Interpretation:

The rate of reaction and the reason for the quicker growth of mold on bread at room temperature compared to the refrigerator should be determined.

Concept introduction:

• Rate of reaction is typically defined as how concentration changes with respect to time.
• Factors affecting the rate of reaction are:

Temperature: Due to high temperature, the movement of atoms become faster and thus, resulting in increasing the chances of colliding and reacting together.

Concentration: Higher the number of atoms, greater is the chance of colliding and reacting together.

Particle size: The large size of the particles will not react as most atoms are stuck inside whereas a large number of small particles has higher chances of colliding and reacting together.

To explain: The rate of reaction definition and the reason for the quicker growth of mold on bread at room temperature compared to the refrigerator.
