NEETChemistryThermodynamics (C)
How can the change in enthalpy (∆H) be calculated for finite changes at constant pressure?
Options
- A∆H = ∆U - ∆PV
- B∆H = ∆U + ∆PV
- C∆H = ∆U * ∆PV
- D∆H = ∆U / ∆PV
Correct answer
B. ∆H = ∆U + ∆PV
Step-by-step solution
The change in enthalpy (∆H) for finite changes at constant pressure is calculated as ∆H = ∆U + ∆PV.
