Problem

The internal energy change in the conversion of 1.0 mole of the calcite form of

\text{CaCO}_3

to the aragonite form is

+0.21 \text{ kJ}

. Calculate the enthalpy change when the pressure is 1.0 bar; given that the densities of the solids are

2.71 \text{ g cm}^{-3}

and

2.93 \text{ g cm}^{-3}

respectively.
