Calculate the Gibbs energy change per mole and per cubic meter.

One heating α-Ti (hcp) transforms to β-Ti (bcc) at 1175 K with enthalpy of transformation equal to 4,480 J/mol. Heat capacities of α-Ti and β-Ti above 300 K are 33.6 and 29.5 J/mol-K, respectively. Calculate the Gibbs energy change per mole and per cubic meter of α-Ti for β-Ti → α-Ti transformation at 1100 K and 1150 K. Density of α-Ti is 4.5 g/ml and its atomic weight is 47.9.
