Energy of activation of forward reaction...

Energy of activation of forward reaction for an endothermic process is 50kJ. If enthalpy change for forward reaction is 20kJ then enthalpy change for backward reaction will be-

A

30 kJ

B

20 kJ

C

70 kJ

D

50 kJ

Text Solution

Verified by Experts

The correct Answer is:
A
For endothermic reaction ,
`E_(a)("backward")=E_(a)("forward")-DeltaH^(0)`
= 50kJ - 20 kJ = 30kJ
