For a reaction, `H_2+I_2hArr 2HI` at 721 K , the value of equilibrium constant is 50. If 0.5 moles each of `H_2` and `I_2` is added to the system the value of equilibrium constant will be :

A

40

B

60

C

50

D

30

Text Solution

Verified by Experts

The correct Answer is:
C
The equilibrium constant does not change when concentration of reactant is changed as the concentration of product also gets changed accordingly.
