The equilibrium of the reaction `N_(2)(g)+3H_(2)(g) hArr 2NH_(3)(g)` will be shifted to the right when:

Options

A. by increasing the concentration of `NH_(3)`
B. by decreasing the pressure
C. by decreasing the pressure
D. by decreasing the concentration of `N_(2) (g) and H_(2)` (g)

Answer

D

Explanation

As forward reaction is accompanied by decrease in the number of moles, applying Le Chatelie'rs principle , increses of pressure will shift the equilibrium in the forward direction, Also , as forward reaction is exothermic , increases of temperature will shift the equilibrium in the forward direction .
