The efficiency of an ideal gas with adiabatic exponent `'gamma'` for the shown cyclic process would be

A

`((2ln2-1))/(gamma//(gamma-1))`

B

`((1-2ln2))/(gamma//(gamma-1))`

C

`((2ln2+1))/(gamma//(gamma-1))`

D

`((2ln2-1))/(gamma//(gamma+1))`

Text Solution

Verified by Experts

`W_(BC)=PDeltaV=nRDeltaT=-nRT_(0)`
`W_(CA)=+2nRT_(0)ln2`
`DeltaQ_(BC)=nC_(p)DeltaT=(nRgammaT_(0))/(gamma-1)`
Hence, efficiency `((2ln2-1))/(gamma//(gamma-1))`
