An engine using 1 mol of an ideal gas initially at 16 L and 276 K performs a cycle consisting of four steps:
1) an isothermal expansion at 276 K from 16 L to 32.2 L ;
2) cooling at constant volume to 168 K ;
3) an isothermal compression to its original volume of 16 L; and 4) heating at constant volume to its original temperature of 276 K .
Find its efficiency. Assume that the heat capacity is 21 J/K and the universal gas constant is 0.08206 L · atm/mol/K = 8.314 J/mol/K.
