A. A = H - TS B. A = E - TS C. A = H + TS D. None of these
Chemical Engineering Thermodynamics (MCQs) 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. Explanation: Helmholtz free energy : A=U−TS dA=−WR So, the decrease in Helmholtz energy denotes maximum work done in an reversible process under isothermal conditions. Show AnswerDiscussion
