Three moles of an ideal gas undergo a cyclic process shown in figure. The work done by the gas during the process is [Take ln ( 2 ) = 0 . 693 ]
Options
- A2.36 R T 0
- B0.58   R T 0
- C1.16 R T 0
- D– 0.58   R T 0
Correct answer
C. 1.16 R T 0
Step-by-step solution
If V 0 be volume of the gas at C , P 0 V 0 = 3 R T 0 W = 3 R ( 2 T 0 ) l n 2 – P 0 V 0 = 6 R T 0 l n 2 – 3 R T 0 = 3 R T 0 [ 2 × 0.693 – 1 ] = 3 R T 0 [ 1.386 – 1 ] = 1.16 R T 0
