The maximum work obtained by an isothermal reversible expansion of 1 mol of an ideal gas at `27^(@)C` from 2.24 to 22.4L is (R = 2 cal)

A

1381.8 cal

B

600 cal

C

138.18 cal

D

690.9 cal

Text Solution

Verified by Experts

The correct Answer is:
A
`w = nRT "ln" (V_(2))/(V_(1))`
`= 1 xx 2 xx 300 x 2.303 "log" (22.4)/(2.4)`
`= 1381.8 cal`
