Question

btain the expression for work done chamical reaction

Answer 1

The work performed by the surroundings on the system as the piston moves inward is given by w = PextΔV. Thus 0.08206 L·atm = 8.314 J and 1 L·atm = 101.3 J. The work done by a gas expanding against an external pressure is therefore negative, corresponding to work done by a system on its surroundings.
