Solution

The correct option is B $a \to e, b \to d, c \to f$
Work done in isobaric process= $\int_{V_{1}}^{V_{2}} P d V$
$= P \int_{V_{1}}^{V_{2}} d V$
$= P (V_{2} - V_{1})$
Work done in isothermal process= $\int_{V_{1}}^{V_{2}} P d V$
$= \int_{V_{1}}^{V_{2}} \frac{n R T}{V} d V$
$= n R T l n (\frac{V_{2}}{V_{1}})$
Work done in adiabatic process= $\int_{V_{1}}^{V_{2}} P d V$
$= \int_{V_{1}}^{V_{2}} k V^{- γ} d V$
where $k = P V^{γ}$
$= n R T \times \frac{T_{1} - T_{2}}{γ - 1}$
Hence correct answer is option D.
