In one stroke of a reciprocating compressor, Nitrogen is isothermally and reversibly compressed in a piston + cylinder from 298 K and 20 bar to 200 bar. Assume 2 moles of gas are processed per stroke, and the molecular weight of the Nitrogen is 28 kg/kmol, compute the heat removal (Q) and work (WEC) required in kJ/kg.
