For the gas phase reaction,
`C_(2)H_(4)+H_(2)hArrC_(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 `H_(2)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
(abcd) The reaction is exothermic, hence increasing temperature will favour backward reaction (i.e., conc. Of `C_(2)H_(4)` increases). Again decreasing pressure, removing `H_(2)` and adding `C_(2)H_(6)` favours backward reaction.
