One mole of an ideal gas Cp = 7/2R and Cv = 5/2R is compressed adiabatically in a piston/cylinder device from 2bar and 25°C to 7 bar. The process is irreversible and requires 35% more work than a reversible adiabatic compression from the initial state to the same final pressure. What is the entropy change of the gas and the entropy generation and lost work?
