Show that an irreversible isothermal expansion of an ideal gas against constant external pressure (P2), from an initial state of P1, V1, T to P2, V2, T, with P2 less than P1, is a spontaneous process by showing that ASuniv is positive. You will need to calculate ASsus and AS surr - upload your calculations for each separately below. You may show that ASuniv is positive graphically. (By calculate, I mean to show that the signs and relative magnitudes of AS sys and AS surr are appropriate. A sketch of the graph is ok.)
