Chapter 15, Problem 15.140SP

Interpretation Introduction

Interpretation:

Whether the given reaction $\text{2NO}\left(\text{g}\right)\rightleftharpoons {\text{N}}_{\text{2}}\left(\text{g}\right){\text{+O}}_{\text{2}}\left(\text{g}\right)$ is exothermic or endothermic in terms of kinetics needs to be explained.

Concept introduction:

A chemical reaction is said to be in equilibrium if there is no further change in its concentration takes place with time. The equilibrium constant is defined as ratio of equilibrium concentration/molarity of product to reactant reaction raised to the power of the respective stochiometric coefficient in the equilibrium reaction.
