For a reaction, P+Q rarr R+S. The value ...

For a reaction, `P+Q rarr R+S`. The value of `DeltaH^(@)` is `-"30 kJ mol"^(-1) and DeltaS" is "-"100 J K"^(-1)"mol"^(-1)`. At what temperature the reaction will be at equilibrium?

A

`27^(@)C`

B

`52^(@)C`

C

`30^(@)C`

D

`45^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
A

`DeltaG=DeltaH-TDeltaS,`
At equilibrium, `DeltaG=0, DeltaH=TDeltaS`
`30000=Txx100`
`T="300 K or "27^(@)C`
