The reaction C(2)H(6)(g) iff C(2)H(4)(g)...

The reaction `C_(2)H_(6)(g) iff C_(2)H_(4)(g)+H_(2)(g)` is at equilibrium in a closed vessel at 1000 K. The enthalpy change `(DeltaH)` for the reaction is 137.0kJ `mol^(-1)`. Which one of the following actions would shift the equilibrium to the right ?

A

Decreasing the volume of the closed reaction vessel

B

Decreasing the temperature at which the reaction is performed

C

Adding an inert gas to the closed reaction vessel.

D

Increasing the volume of the closed reaction vessel.

Text Solution

Verified by Experts

The correct Answer is:
D

According to Lechatelier principal on increasing volume of closed vessel equilibrium will shift towards right.
