For the synthesis of ammonia by the reaction `N_(2)+3H_(2)hArr2NH_(3)` in the Haber's process ,the attainment of equilibrium is correctly predicated bt the curve

Options

A.
B.
C.
D.

Answer

A

Explanation

For the reaction,
`N_(2)+3H_(2) hArr 2NH_(3)`
The molar concentrations of both `N_(2)` and `H_(2)` will fall with time till equilibrium is reached. On the other hand,molar concentration of product, `NH_(3)` will increase from zero to maximum at equilibrium. After equilibrium, molar concentrations of `N_(2),H_(2)` and `NH_(3)` will become constant.
