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.
