For the reaction H(2)(g)+I(2)(g) hArr ...

For the reaction
`H_(2)(g)+I_(2)(g) hArr 2HI(g)`
The equilibrium constant `K_(p)` changes with

A

Total pressure

B

Catalyst

C

The amounts of `H_(2)` and `I_(2)` present

D

Temperature

Text Solution

Verified by Experts

The correct Answer is:
D
The equilibrium constant does no change at all with changes in concentrations, volume, pressure, presence of catalyst, etc. It changes only with changes in temperature of the system. For endothermic reaction, the value of K increases with increase in temperature and vice versa. For exothermic reaction, the value of K decreases with increase in temperature and vice versa.
