Problem- Calculate Delta S of the universe and Delta G of the system for the change in state that occurs when 2mol of an ideal gas at 300K occupying a volume of 24.6L expands isothermally against an opposing pressure of 1atm to reach equilibrium.
I just need a general explanation of it please- Thanks!
