Three moles of an ideal gas at 27.0ºC expands isothermally from an initial volume of 20.0 dm3 to a final volume of 60.0 dm3. Calculate w for this process a) for expansion against a constant external pressure of 1.00 x 105 Pa and b) for a reversible expansion.

A ) w = – Pext (V2-V1)= – 1 atm (60-20 )l = -40 l atm = -4053 Joules work was done .B) For a reversible expansionw = -nRt ln (V2/V1)= – 3 * 8.314 * 300 *ln (60/20) J= – 8156.034 joules work…
