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 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.
