An increase in pressure does not affect the reaction because the moles of reactants and products or the pressure of the forward reaction are equal at equilibrium.
<h3>What is chemical equilibrium?</h3>
A chemical reaction is in equilibrium if the rate of the backward reaction and the forward reaction are equal.
Pressure affects the equilibrium position of chemical reactions involving gases.
For the given reactions in equilibrium, moles of reactants and products and hence, the pressure of the forward reaction are equal at equilibrium, therefore, an increase in pressure does not affect it.
Therefore, an increase in pressure will only affect the equilibrium of a reaction in which the pressure varies in the forward and backward reaction.
