What is the free energy charge `(DeltaG)` when 1.0n mole of water at ` 100^(@)C` and 1 atm pressue is converted
into steam at `100^(@)C` and 2 atm pressure ?

A

zero cal

B

540 cal

C

517.13 cal

D

510 cal

Text Solution

Verified by Experts

The correct Answer is:
C

`DeltaG_(2) = nRT In ((P_(2))/(P_(1)))`
`= 1 xx 2 xx 373 xx 0.6 93`
` = 517 "cal"`
