Solve : `DeltaH=10k " cal mol"^(-1),DeltaS=20 " cal deg"^(-1)mol^(-1) and T = 300k. " Then " DeltaG= ? `

A

`-18,000 " cals mol"^(-1)`

B

`18,000 " cals mol"^(-1)`

C

`-16,000 " cals mol"^(-1)`

D

`4,000 " cals mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
D
`DeltaG=DeltaH-TDeltaS`
`DeltaG=-10,000-(300xx20)" "[10k " cal mol"^(-1)=10,000"cals mol"^(-1)]=`
`=10,000-6000`
`=4,000" cals mol"^(-1)`
