Pick out the correct equation relating 'F' and 'A'.
Answer & Solution
Correct Answer:
Option
A
Here the $$F$$ is Gibbs free energy and $$A$$ is Helmholtz free energy.
So, $$F=H-TS$$ and $$A=U-TS$$
$$\eqalign{ & \Rightarrow F = H + A - U \cr & \Rightarrow F = A + PV \cr} $$
So, $$F=H-TS$$ and $$A=U-TS$$
$$\eqalign{ & \Rightarrow F = H + A - U \cr & \Rightarrow F = A + PV \cr} $$
