For the reaction `N_(2)(g)+3H_(2)(g) hArr 2NH_(3)(g), DeltaH=-93.6" kJ "mol^(-1)`, the concentration of `NH_(3)` at equilibrium can be increased by :
(1) lowering the temperature
(2) low pressure
(3) excess of `N_(2)`
(4) excess of `H_(2)`

A

(2) and (4) are correct

B

(2) only is correct

C

(1), (2) and (3) are correct

D

(1), (3) and (4) are correct

Text Solution

Verified by Experts

The correct Answer is:
D
`N_(2)(g)+3H_(2)(g) hArr 2NH_(3)(g)`
`DeltaH=-93.6" kJ "mol^(-1)`
This reaction is exothermic therefore the concentration of `NH_(3)` can be increased by lowering the temperature, high pressure, `(Deltan lt 0)` excess of `N_(2) and H_(2)`.
