An ideal gasa undergoes through folowing cyclic procees.
1-2 : Reversible adialbatic comparession from
`P_(1)V_(1)T_(1)"to"P_(2)V_(2)T_(2)`
2-3 : Reversible isochoric heating from
`P_(2)V_(2)T_(2)" to " P_(3)V_(3)T_(3)`
3-4 Reversible adialbatic expansion from
`P_(3)V_(3)T_(3)" to " P_(4)V_(4)T_(4)`
4-1 Reversible isochoric cooling from
`P_(4)V_(4)T_(4)" to " P_(1)V_(1)T_(1)`
Eefficiencyof the cycle is :
A. `((T_(4)-T_(1))/(T_(3)-T_(2)))`
B. `1-T_(1)/(T_(2))`
C. `1-(V_(2)/(V_(1)))^(gamma-1)`
D. `1-|Q_(4-1)/(Q_(2-3))|`
