As gas expands from 1.00 L to 2.50 L against constant pressure of 820 torr. Calculate the change in internal energy for the gas, if 120 J of heat is transferred to the gas during the expansion.
When equilibrium is reached at 700C, the total pressure of the system is found to be 4.00 atm. If the equilibrium constant Kp for this reaction is equal to 1.52,
