Gibbs-Helmholtz equation is__________________?
Correct answer: A. ΔF = ΔH + T [∂(ΔF)/∂T]P
- A. ΔF = ΔH + T [∂(ΔF)/∂T]P
- B. ΔF = ΔH - TΔT
- C. d(E - TS) T, V < 0
- D. dP/dT = ΔHvap/T.ΔVvap
Explanation
The Gibbs-Helmholtz relation can be written as ΔG = ΔH + T[∂(ΔG)/∂T]ₚ; the option uses F for the free-energy function. The other expressions are not the Gibbs-Helmholtz equation, although option d resembles the Clapeyron equation.
