50 mol of nitrogen gas initially at 10°C and 100 bar Hirogen gas initially at 10°C and 100 bar are heated at constant pressure to a final temperature of 300°C. Using an approp ature of 300°C. Using an appropriate generalized correlation calculate the armount or heat required for the process. Note that nitrogen is not an ideal gas under conditions. Over this temperature range you may assume Cple of nitrogen to be constant equal to 30 J/mol K.

At what temperature is the root-mean-square speed of nitrogen molecules equal to the root-mean-square speed of hydrogen molecules at 46 oC? (Hint: The molar mass of hydrogen atoms is 1.008 g/mol and of nitrogen atoms is 14.007 g/mol. The molar mass of H2 is twice the molar mass of hydrogen atoms, and similarly for N2.) The answer is in degree C.
