For a Carnot engine with 10 moles of ideal gas (Cv = 1.5 nR) and operating between a hot reservoir of 500 K and a cold reservoir of 300 K,

a) What would be the heat exchanges (q1) and entropy change (∆S1) for step 1, where the gas reversibly and isothermally expands to double its volume (V2 = 2 V1) at 500 K?

b) What would be the heat exchanges (q3) and entropy change (∆S3) for step 3, where the gas is reversibly and isothermally compressed to half its volume (V4 = 0.5 V3) at 300 K?

c) What would be the net work done by this Carnot engine within each cycle?

d) What would be the efficiency of this Carnot engine?
