is the equation U(total)=(3/2)n*R*T only used when there has been an isothermal reversible expansion reaction?

The change of internal energy of a system is zero in isothermal expansion. This formula is related to the equipartition theory and can be used to calculate the internal energy of molecules or atoms by taking into account rotational and translational energy.
