2.)

A mixture of hydrocarbons is compressed steadily from 100 kPa and 20°C to 1000 kPa in

a reversible, isothermal compression process. The mixture consists of (by mass) 60%

methane, 25% propane, and 15% butane. Assume constant specific heats and determine;

a) the work required (kJ/kg), and

b) the heat loss (kJ/kg) for this compression process.
