Chapter 15, Problem 57E

Interpretation Introduction

Interpretation:

The concentration of reactant, ${\text{SbCl}}_{\text{5}}$ is to be calculated with help of concentration of product and equilibrium constant value.

Concept Introduction:

Equilibrium may be defined as a state of a reaction mixture at which rate of forward reaction is equal to rate of backward reaction.

Equilibrium constant is dimensionless quantity.

The unit of concentration of reactant species at reaction mixture is $\text{M}$.

The expression of equilibrium constant is ratio of concentration of product to the concentration of reactant.

${\text{K}}_{\text{eq}}\text{= }\frac{\left[\text{product}\right]}{\left[\text{reactant}\right]}$ where, $\left[\text{product}\right]$ is concentration of product and $\left[\text{reactant}\right]$ is concentration of reactant.
