Calculate the work done when 1 mol of an ideal gas is compressed reversibly 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.+3.457 kJ✓ Correct

Explanation

For isothermal reversible expansion, work done is given by the following formula- THERMODYNAMICS AND THERMOCHEMISTRY 32 1 2 P W nRTln P 1 W 1 8.314 300 ln 4 W 3457.69J 3.457 kJ >> x x x Also, since the gas is compressible, W 3.457kJ Thus, the correct option is (d) None of these
