Interpretation Introduction

Interpretation:

The equilibrium concentration of ${\text{H}}_{\text{2,}}{\text{I}}_{\text{2}}$ and HI has to be calculated from the given initial concentration of HI, ${\text{H}}_{\text{2}}\text{and}{\text{I}}_{\text{2}}$

Concept introduction:

Equilibrium constant ( ${\text{K}}_{\text{C}}$): It is the ratio of product of product concentration raised to powers of their coefficient to product of reactant concentration raised to powers of their coefficient.

For a general reaction $\text{aA+}\text{}\text{}\text{}\text{bB}\stackrel{}{\to }\text{cC}\text{+}\text{dD}$,

${\text{K}}_{\text{C}}\text{=}\frac{{\left[\text{C}\right]}^{\text{c}}{\left[\text{D}\right]}^{\text{d}}}{{\left[\text{A}\right]}^{\text{a}}{\left[\text{B}\right]}^{\text{b}}}$      c, d, a and b are the co-efficient.
