Which of the following relations are correct?
A
U = q + p 
V C and D only
B
G = 
H - T 
S B and C only
C
S = 
A and B only
D
H = 
U - 
nRT Choose the most appropriate answer from the options given below : B and D only
Text Solution
Verified by ExpertsThe correct answer is:
B
Only and are correct.
G = H-TS At constant T
G = 
H - T 
S
First law is given by
U = Q+W If we apply constant P and reversible work.
U = Q-P 
V
By definition of entropy change
At constant T
H = U + PV
For ideal gas
H = U + nRT
At constant T
H = 
U + 
nRT
