A thermodynamic process of one mole ideal monoatomic gas is shown in figure. The efficiency of cyclic process `ABCA` will be

A

0.25

B

0.125

C

0.5

D

0.077

Text Solution

Verified by Experts

The correct Answer is:
D
`W=(1)/(2)P_(0)V_(0), T_(A)=T_(0),T_(B)=2T_(0),T_(C)=4T_(0)`
Heat supplied =`Q_(AB)+Q_(BC)=C_(V)T_(0)+C_(p)2T_(0)`
`=(13)/(2)RT_(0)=(13)/(2)P_(0)V_(0)`
`therefore` Efficiency of the cyclic process
`((1)/(2) P_(0)V_(0))/((13)/(2)P_(0)V_(0))xx100=(1)/(13)xx100=7.7%`
