If 1 mole of an ideal gas expands isothermally at `37^(@)C` from 15 litres to 25 litres, the maximum work obtained is `:`

A

12.87 J

B

6.43 J

C

8.57 J

D

2.92 J

Text Solution

Verified by Experts

The correct Answer is:
A
`w= -2.303 nRT log""(V_(2))/(V_(1))= -2.303 xx 1 xx 0.821 xx 310 xx log((25)/(15))= -58.61 xx 0.22 = -12.87 J` (-ve sign shows work of expansion i.e work done by the system )
