Calculate the work done (in joules) when `0.2` mole of an ideal gas at `300 K` expands isothermally and reversible from an initial volume of `2.5` litres to the final volume of `25` litres.

A

996

B

1148

C

11.48

D

897

Text Solution

Verified by Experts

The correct Answer is:
b
` w = - 2.303nRT log. (V_(2))/(V_(1))= - 2.303 xx 0.2 xx 8.314 xx 300 log. ( 25)/( 2.5) = - 1148 J`
