Benzene vapour at 580°c is cooled and converted to a liquid at 25°c in a continuous condenser. the condensate is drained into 1.75 m drums, each of which takes te minutes to fill. the boiling temperature of benzene is 80.1°c and the heat o evaporation is 30.765 kj mol1. the specific gravity of the liquid benzene is 0.879, the heat capacities of benzene can be calculated using the expressions (t is in degrees celsius): 5 liquid benzene: c 126.5x 10 +23.4x 10 t vapour benzene: c 74.06x 103 +32.95x 10s t-25.20x 10 t2 +77.57x 1012t3 the units for the cp values are kj mol k1 draw the hypothetical process path from vapour to liquid benzene under the conditions given. (a) 5 marks] calculate the specific enthalpies associated with each path in the diagram in (a) (b) [8 marks] calculate the flow rate of liquid benzene product in mol s1 (c) [3 marks] calculate the rate (kw) at which heat is transferred from the benzene in the condenser.
