Chapter 12, Problem 3CR

Interpretation Introduction

Interpretation:

The terms system and the surrounding are to be explained. The direction of heat in endothermic reaction is to be predicted. Whether the reaction is exothermic or endothermic if a reaction between ionic solutes is performed in aqueous solution and the temperature of the solution is increased is to be stated.

Concept Introduction:

The chemical reaction in which energy is released during the formation of products is known as exothermic reactions. The energy released during the reaction is denoted by $\text{Δ}\text{H}°$. Exothermic and endothermic reactions are opposite to each other. The value of $\text{Δ}\text{H}°$ for exothermic and endothermic reactions is negative and positive respectively.
