Chapter 18.1, Problem 5LC

Interpretation Introduction

Interpretation: The reason for the quick spoilage of food in the room is to be stated.

Concept Introduction: A chemical reaction only occurs when the reactants are converted to the products. The speed or the rate at which the reaction proceeds is called the rate of the reaction. Temperature, catalyst, surface area, and concentration of the reactants are the four factors that affect the rate of a chemical reaction.

Answer to Problem 5LC

Due to an increase in the temperature, the food stored at room temperature gets spoiled.

Explanation of Solution

An increase in temperature increases the rate of a chemical reaction by providing the energy for the breaking of the bonds. On the other hand, the temperature in the refrigerator is less as compared to the room temperature; thus, the rate is also lower. That is why the food which is stored at room temperature spoils quickly and the food which is stored in the refrigerator stays fresh for a long period.
