For the gas phase reaction C2H4+H2⇌C2H6, ΔH = -32.7kcal carrie

Question

For the gas phase reaction

C_{2} H_{4} + H_{2} ⇌ C_{2} H_{6},

Δ H

= -32.7kcal carried out in a vessel, the equilibrium concentration of

C_{2} H_{4}

can be increased by -

Options:

A . increasing the temperature

B . Increasing concentration of H2

C . Decreasing temperature

D . Increasing pressure

Answer: Option A
:
A
Since backward reaction is endothermic, increase in temperature favors backward reaction
