For the gas phase reaction C(2)H(4)+H(...

For the gas phase reaction
`C_(2)H_(4)+H_(2) hArr C_(2)H_(6)(DeltaH=-32.7 "kcal")`
carried out in a vessel, the equilibrium concentration of `C_(2)H_(4)` can be increased by

A

Increasing the temperature

B

Decreasing the pressure

C

Removing some `C_(2)H_(6)`

D

Adding some `H_(2)`

Text Solution

Verified by Experts

The correct Answer is:
A,B
According to Le-Chatelier's principle, the increase of temperatureor decrease of pressure will favour the backward reaction.
