As the temperature is lowered towards the absolute zero, the value of ∂(ΔF)/∂T, then approaches_______________________?
Correct answer: B. Zero
- A. Unity
- B. Zero
- C. That of the heat of reaction
- D. Infinity
Explanation
The temperature derivative of Helmholtz free energy is related to entropy, since (∂F/∂T)V = −S. Entropy approaches zero as absolute zero is approached, so the derivative of the reaction free-energy change approaches zero.
