Calculate the entropy change when heating 1.2 mol SO2 from temperature T1 = 175K to T2 = 285K, at P = 1.013*10^5 Pa, molar heat of melting ΔHmt. = 7.434 J/mol and the molar heat of evaporation is ΔHgas. = 25.05 J/mol. The dependence of the heat capacity on the temperature for the gaseous state Cp = a + W + s*/ T^2 taken from the reference book: Wed(s) = 11,47 J/mol*K, Wed(liquid) = 13,99 J/mol*K
