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 temperature

C

Removing some `H_(2)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
A, C, D
Applying Le Chatelier's principle, when the temperature is increased, the equilibrium shifts in the direction of the endothermic reaction. When the pressure is increased, the equilibrium shift in the direaction of less number of moles. The removal of reactant and addition of a product shift the equilibrium in the backward direction.
