2.30 moles of an ideal gas with molar heat capacity at constant volume of 12.47 J/K*mol is expanded irreversibly and adiabatically from an initial pressure of 10.0 kbar against a constant external pressure of 1.00 bar to a final pressure of 50.0 bar. The initial temperature is 500 K. Calculate the following:
a. The final temperature of the gas in Kelvin
b. q in Joules
c. delt U in Joules
d. delta H in Joules
