Options

A. change in pressure and temperature
B. change in temperature and concentration of `N_(2)`
C. change in pressure and concentration of `N_(2)`
D. change in pressure, temperature and concentration of `N_(2)`.

Answer

D

Explanation

`N_(2)+3H_(2)hArr2NH_(3),DeltaH=-22.08" kcal"`
The reaction is exothermic accompanied with decrease in number of moles. So, the equilibrium is affected by temperature, pressure and concentration.
