If `Delta H = 35.5` kJ/mol and `Delta S = 83.6` J/mol K. At what temperature the reaction will be spontaneous?

A

`T gt 425 K`

B

Each temperature

C

`T lt 298` K

D

`T lt 425 K`

Text Solution

Verified by Experts

The correct Answer is:
A
`Delta G = Delta H - T Delta S`
`T= (Delta H)/( Delta S) = (35.5 xx 1000)/( 83.6) = 425K`
`therefore` Reaction will be spontaneous at temperature `T gt 425 K`.
