Which equation represents the change in enthalpy (∆H) during a chemical reaction?

Options

  1. A∆H = qV - P∆V
  2. B∆H = qP - ∆U
  3. C∆H = H2 - H1
  4. D∆H = U2 - U1

Correct answer

C. ∆H = H2 - H1

Step-by-step solution

The change in enthalpy (∆H) during a chemical reaction is represented as ∆H = H2 - H1.
