Calculate δs0 for the following processes:
a.) heating 1 mol of benzene(liquid) from 298k to 353 k at 1 bar pressure, neglecting any t-dependence of cp.
b.) vaporizing the resulting benzene (l) to benzene(g) at its normal boiling point of 353 k, at 1 bar pressure. note: its latent heat of vaporization at 353 k is 30.8 kj/mol.
c.) the total process of steps (a) and (b) both.

Asteam power plant operates on an ideal reheat rankine cycle between the pressure limits of 15 mpa and 10 kpa. the mass flow rate of steam through the cycle is 12 kg/s. steam enters both stages of the turbine at 500°c. if the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10 percent, determine (a) the pressure at which reheating takes place, (b) the total rate of heat input in the boiler, and (c) the thermal efficiency of the cycle. also, show the cycle on a t-s diagram with respect to the saturation lines. (2.15 mpa; 45.0 mw; 42.6%)
