Chapter 12, Problem 80QP

Interpretation Introduction

Interpretation:

The reaction represented by the molecular level diagram proceeds in a forward or reverse direction, or if it is already at equilibrium is to be identified.

Concept Introduction:

Reaction quotient $\left(Q\right)$ is the result obtained by substituting non-equilibrium concentrations in the equilibrium constant equation. If the value of the reaction quotient is greater than the value of the equilibrium constant, it indicates that the reactant concentration is less and more product is formed. Therefore, the reaction proceeds in a reverse direction to attain equilibrium.
