4. 50 mol of nitrogen gas initially at 10°C and 100 bar are heated at constant pressure to a final temperature of 300°C. Using an appropriate generalized correlation calculate the amount of heat required for the process. Note that nitrogen is not an ideal gas under these conditions. Over this temperature range you may assume Cp of nitrogen to be constant equal to 30 J/mol K
