Expert Solution

Step 1

Equilibrium constant is the ratio of concentration of products to the concentration of reactants raised to the power of their respective coefficients.

For example;

$a X \Leftrightarrow b Y$

Thus, $K_{c} = \frac{{[Y]}^{b}}{{[X]}^{a}}$

Here, [ ] denotes the concentration of each specie and a, b are the coefficients of X and Y, respectively.

At any time, if the concentration of reactant (X) is higher than the concentration of product (Y), then;

$\frac{{[Y]}^{b}}{{[X]}^{a}} < 1 \Rightarrow K_{c} < 1$

At any time, if the concentration of product (Y) is higher than the concentration of reactant (X), then;

$\frac{{[Y]}^{b}}{{[X]}^{a}} > 1 \Rightarrow K_{c} > 1$

At any time, if the concentration of product (Y) is equal to the concentration of reactant (X), then;

$\frac{{[Y]}^{b}}{{[X]}^{a}} = 1 \Rightarrow K_{c} = 1$
