Right. I started using the Gibbs equation: $TdS=PdV+dU$ Using the relation: ∂U/∂v|T=T∂P/∂T|v-P And making some manipulations I obtained: dQa-b=cvdT+PdV Considering an ideal gas. Using the ideal gas state equation, ΔT=0 and PdV=Wa-b. And I found ΔQ=Wa-b=3P0V0/4 But i think there is something...

I have to calculate the efficiency of the above cycle for an ideal gas, that goes at the order a-b-c-a: I know that the answer is 16/97 but I can't calculate the heat in the a-b stage.
