Helmholtz free energy (A) is defined as
A. A = H - TS
B. A = E - TS
C. A = H + TS
D. None of these
Answer: Option B
Solution (By Examveda Team)
Helmholtz free energy :\[\begin{array}{l} A = U - TS\\ dA = - {W_R} \end{array}\]
So, the decrease in Helmholtz energy denotes maximum work done in an reversible process under isothermal conditions.
