In calculating the enthalpy change, ∆H, of an experiment involving solutions, the mass of the solution, m, specific heat capacity of the solution, c, and the temperature change, ∆T, are needed. ∆T = Tfinal - Tinitial Which expression for ∆H is correct?
A∆H = mc/∆T
B∆H = -mc/∆T
C∆H = mc∆T
D∆H = -mc∆T
✓ Correct answer
D: ∆H = -mc∆T
