Chapter 14, Problem 110AP

Interpretation Introduction

Interpretation:

The ranking(slowest to fastest) for the rate of different reactions, change in enthalpy foreach reaction is to be determined by considering the given potential energy profiles and it is to be stated whether the reactions are endothermic or exothermic.

Concept introduction:

Rate of a reaction is the speed of that reaction at which reactants are converted into the products.

When energy is released in a reaction, the reaction is called an exothermic reaction $\left(\Delta \text{H}=-\text{ve}\right)$ and the reactions in which energy is absorbed are calledasendothermicreactions $\left(\Delta \text{H}=+\text{ve}\right)$.
