For the reaction A rarr B , DeltaH^(@) ...

For the reaction `A rarr B , DeltaH^(@) = 7.5 mol^(-1)` and `DeltaS^(@) = 2.5 J mol^(-1)`. The value of `DeltaG^(@)` and the temperature at which the reaction reaches equilibrium are, respectively.

A

`0 kJ mol^(-1)` and `400 K`

B

`-2.5 kJ mol^(-1)` and `400 K`

C

`2.5 kJ mol^(-1)` and `200 K`

D

`0 kJ mol^(-1)` and `300 K`

Text Solution

Verified by Experts

The correct Answer is:
D
At equation `DeltaG^(@) = 0`
`:. T = (DeltaH)/(DeltaS) = (7.5 xx 1000)/(25) = 300 K`
