An ideal gas undergoes a cyclic process ...

An ideal gas undergoes a cyclic process as shown in figure .

A

`-5 kJ mol^(-1)`

B

`5 kJ mol^(-1)`

C

`18 kJ mol^(-1)`

D

`-18 kJ mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
b
`DeltaU_(AB) = q+W = 2-5 = -3 kJ//mol`
`DeltaU =0 = DeltaU_(AB) + DeltaU_(BC) + DeltaU_(CA)`
`rArr 0=-3 -5 + DeltaU_(CA) rArr DeltaU_(CA) =8 kJ//mol`
`DeltaU_(CA) =q +W`
`rArr 8 = q_(CA) + 3 = q_(CA) = 5 kJ//mol`
