Answer to Question #89295 in Molecular Physics | Thermodynamics for Shivam Nishad

Question

What is enthalpy of a reaction ? Write down the
expression for enthalpy in terms of internal energy, pressure and volume.

Answer 1

Enthalpy ( H ) is the sum of the internal energy ( U ) and the product of pressure and volume ( PV ) given by the equation:

H = U + PV.

Enthalpy can be define as the total energy that the substance has at a particular state.
