Chapter 6, Problem 42P

Interpretation Introduction

Interpretation:

Factors affecting the rate of a reaction needs to be determined.

Concept introduction:

Enthalpy, $\Delta H$ is defined as the energy absorbed or released in a reaction. Enthalpy can also describe as the difference between the energy of the products and the energy of the reactants.

Energy difference between the reactants and the transition state is known as activation energy ( E_a , see the figure below). Activation energy, E_a is the minimum energy required by the reactants to initiate a reaction.
