A gas undergoes a reaction at constant pressure that causes its volume to increase. The change in enthalpy for this reaction is AH = +200/J, and the pressure times the change in volume is PAV = +300kJ. Which statement about the reaction is true? O None of the above. 100 kJ is added to the gas as heat, and the internal energy decreases by 200 KJ. O 200 kJ is released from the gas as heat, and the internal energy increases by 100 KJ. 100 KJ is added to the gas as heat, and the internal energy increases by 200 KJ
