As 2 moles of sirenite is heated under a constant pressure of 1
atm it undergoes a solid phase transition, at a temperature of 750
K, from α-sirenite to β-sirenite. The molar specific heat capacity
of sirenite varies with thermodynamic temperature, T, such that Cvm
= 2.50 x 10-6 T^2 Jmol-1K-1.
a) Calculate the entropy change of the sirenite between the
transition temperature of 750 K and room temperature (300 K).
b) By what factor does the number of accessible...
