Calculate the work done when 1 mol of an ideal gas is compressed reversible from 1 bar to 4 bar at a constant temperature of 300 K.

A

4.01 kJ

B

`- 8.02 kJ`

C

18.02 kJ

D

3.458 kJ

Text Solution

Verified by Experts

The correct Answer is:
D
`w = - 2.303 nRT "log" (p_(1))/(p_(2))`
`= - 2.303 xx 1 xx 8.314 xx 300 "log" (1)/(4)`
`3458.3 J = 3.458 kJ mol^(-1)`
