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

A

`- 1381.8 n cal `

B

`-600 n cal `

C

`-690.9 n cal `

D

`-6000 n cal`

Text Solution

Verified by Experts

The correct Answer is:
A
`W=-2.303 nRT log_10 (V_2)/(V_1)`
`W =-2.303 nRT log_10 (22.4)/(2.24)`
`W =- 2.303 xx n xx 2 xx 300 log_10 10 = -1381.8 n ` cal.
