Chapter 18, Problem 10E

Interpretation Introduction

Interpretation:

Whether the $\text{ΔE}$ for the reaction given in Figure $\text{18-3}$ is positive or negative is to be predicted. Whether the reaction is exothermic or endothermic is to be predicted. The algebraic expressions of $\text{Δ}\text{E}$ and the activation energy of the reaction, using the letters a, b, and c, are to be stated.

Concept introduction:

According to collision theory, reactant molecules collide with proper orientation and sufficient energy to form products. Activation energy can be defined as the amount of energy that is required to convert reactant molecules into products.
