In which of the following equilibrium reactions, the equilibrium reactions, the equilibrium would shift to the right, if total pressure is increased

Options

A. `N_(2)(g)+3H_(2)(g) Leftrightarrow 2NH_(3) (g)`
B. `I_(2) (g)+H_(2)(g) Leftrightarrow 2HI(g)`
C. `N_(2) (g)+O_(2) Leftrightarrow 2NO(g)`
D. `N_(2)O_(4) (g) Leftrightarrow 2NO_(2) (g)`

Answer

A

Explanation

Pressure increases, equilibrium moves in the direction where the no of moles is less
