consider the reaction below. 2nh3(g) ⇌ n2(g) + 3h2(g) which is most likely the effect to the forward reaction if there is an increase in pressure of the system? the reactant surface area increases. the reaction rate decreases. the reaction is not affected at all. the reaction stops completely.

Answer

Explanation:

Step1: Analyze the reaction

The reaction $2NH_{3(g)}\leftrightarrow N_{2(g)}+3H_{2(g)}$ has 2 moles of reactant gas and 4 moles of product gas.

Step2: Apply Le - Chatelier's principle

According to Le - Chatelier's principle, when pressure is increased, the system will shift in the direction that reduces the number of moles of gas. Here, the reverse reaction (towards reactants) has fewer moles of gas. So, the forward reaction rate decreases as the system tries to counteract the increase in pressure.

Answer:

The reaction rate decreases.
