For the gaseous reaction, `C_(2)H_(4)+H_(2)hArr C_(2)H_(6),DeltaH=-130kJmol^(-1)` carried in a closed vessel, the equilibrium concentration of the `C_(2)H_(6)` can definitely be increased by

A

Increasing temperature and decreasing pressure

B

Decreasing temperature and pressure both

C

Increasing temperature and pressure both

D

Decreasing temperature and increasing pressure

Text Solution

Verified by Experts

The correct Answer is:
D
For exothermic reaction decrease in temperature is favourable to condition, on increasing pressure equilibrium shift in the direction towards lesser number of moles.
