Answer

Brief Explanations:

According to Le - Chatelier's principle, for a gas - phase reaction, an increase in pressure shifts the equilibrium towards the side with fewer moles of gas. In the given reaction (2NH_{3(g)}\rightleftharpoons N_{2(g)}+3H_{2(g)}), the reactant side has 2 moles of gas and the product side has 4 moles of gas. An increase in pressure will shift the equilibrium in the reverse direction, which means the forward reaction rate decreases.

Answer:

The reaction rate decreases.
