(a)-905 kJ/mole (b)-895 kJ/mole (c) 895 kJ/mole (d) 905 kJ/mole One mole of an ideal gas initialy at 300 K and a pressure of 10 atm undergoes adiabatic expansion. () reversibly (11) irreversibly against a constant external pressure of 2 atm until the final pressure becomes equal to the external pressure. Fnd the value of ASvstern for (1) and (1i) in the terms of R (heat capacity at constant volume is Cv= 1.5 R). Calculate the AH and AS, for the process stem
