The correct answer is B.) The reaction rate decreases.

I know this is the right answer because i just did the quiz.

Jayleen · Answer 2

The position of the equilibrium will shift towards the products. Thus, when pressure is increased the rate of the forward reaction is increased.

Explanation:

For the reversible response:

N2 (g) + 3H2 (g) ⇌ 2NH3 (g) + heat.

The equilibrium moves forward way by expanding pressure and diminishing temperature. As indicated by the Le-Chatalier principle when equilibrium is disturbed by a change, the system will try to nullify the impact of change to restore the balance. Subsequently, when pressure is expanded, the equilibrium will move toward a path in which there is a decrease in the number of moles of vaporous substances. This will invalidate the impact of expanded pressure. This occurs the forward way. Also for an exothermic response, when the temperature is diminished, the equilibrium shifts in forwarding direction.
