For the reversible reaction,
N_2(g) + 3H_2(g) $$\rightleftharpoons$$ 2NH_3(g) + heat

The equilibrium shifts in forward direction

by increasing the concentration of NH_3(g)

by decreasing the pressure

by decreasing the concentrations of N_2(g) and H_2(g)

by increasing pressure and decreasiing temperature.

For a given exothermic reaction, K_p and K'_p are the equilibrium constants at temperatures T₁ and T₂, respectively. Assuming that heat of reaction is constant in temperature range between T₁ and T₂, it is readily observed that

K_p > K'_p

K_p < K'_p

K_p = K'_p

K_p = $${1 \over {k{'_p}}}$$
