The activation for the reverse reaction ...

The activation for the reverse reaction XY, if YX is an exothermic reaction and `E_a` for Y is 39.5 kJ per mole and the heat of the reaction is 71.7 kJ

A

`111.2 `

B

`32.2 `

C

`91.2 `

D

`47.2 `

Text Solution

Verified by Experts

The correct Answer is:
A
Hint : For exothermic reaction, `E_a` (backward) = `E_a` (forward) + `DeltaH` (magnitude) `39.5 + 71.7=111.2 kJ `
