4. Consider the following reaction used as a rocket fuel:
(CH3)2N2H2 (s) + N2O4 (l) ⇌ 2CO2 (g) + 3N2 (g) + 4H2O (g)
Kp for this reaction is so large you can assume it goes to completion. The gases produced by this reaction were
collected in a closed, 118 L vessel, and at equilibrium, the total pressure was 2.50 atm and the temperature was
