5. A mixture consisting of 100. moles of hydrogen gas and 2500. moles of air (80.0 mol % nitrogen gas and 20.0 mol % oxygen gas), initially at 25°C, reacts to produce water vapor (and no nitrogen oxides). The pressure is constant at I atm, and the system is adiabatic (no heat exchange between the system and surroundings). The molar heat capacities are: 5.9 cal/mol°C for water vapor; 6.9 cal/mol°C for N2 and O2. Calculate the maximum temperature achieved by this system.
