6. A gas undergoes a reaction at constant pressure that causes its volume to increase. The change in enthalpy for this reaction is ?H= +200 kJ, and the pressure times the change in volume P?V is + 300 kJ Which statement about this reaction is true? A. 100 kJ is added to the gas as heat, and the internal energy increases by 200 kJ B. 100 kJ is added to the gas as heat, and the internal energy decreases by 200 kJ C. 200 kJ is released from the gas as heat, and the internal energy increases by 100kJ D. 200 kJ is released from the gas as heat, and the internal energy decreases by 100kJ E. None of the above 7. If 3 mols of nitrogen (N$_2$) are placed in a cubical box 24cm on each side, at 2.2 atm of pressure. What is the rms speed of nitrogen molecules? (1 atm = 1.013x10$^5$ Pa) A. 468 m/s B. 573 m/s C. 191 m/s D. 331 m/s E. 100 m/s
