One mole of an ideal gas is expanded irreversibly from an initial pressure of 2 atm to a final pressure of 1 atm at a temperature of 300 K . Let q_ irr , S_ sys and S_ surr represent the magnitude of the heat transfer, the entropy change of the system, and the entropy change of the surrounding respectively. Assuming that the surrounding does not perform any work, the correct relation(s) is/are ( R is the universal ga
