The standard reaction Gibbs energy for...

The standard reaction Gibbs energy for a temperature T is given by
`Delta_(r)G^(@)= A-Bt`
Where A and B are non-zero constants.
Which of the following is TRUE about this reaction ?

A

Exothermic if `B lt 0`

B

Exothermic if `A gt 0 and B lt 0`

C

Endothermic if `A lt 0 and B gt 0`

D

Endothermic if `A gt 0`

Text Solution

Verified by Experts

The correct Answer is:
D
`Delta G ^(0) = Delta H ^(0)-T Delta S ^(0)`
`A = Delta H ^(0)`
`B= Delta S ^(0)`
For endothermic Reaction `Delta H gt 0`
