For a constant pressure reversible process, the enthalpy change (ΔH) of the system is___________________?
Correct answer: C. ∫ Cp.dT
- A. Cv.dT
- B. Cp.dT
- C. ∫ Cp.dT
- D. ∫ Cv.dT
Explanation
At constant pressure, the enthalpy change is obtained by integrating the heat-capacity relation, ΔH = ∫Cp dT. If Cp is constant, this reduces to CpΔT.
