Consider the equilibrium N2 (g) + O2 + Br2 (g) <-----> 2NOBr (g). Calculate the equilibrium constant (Kp) for this reaction given the following information (at 298K):
2NO (g)+ Br2 (g) <------> 2NOBr (g) KC = 2.0
2NO (g)<------>N2 (g) + O2 (g) kc=2.1E30
Using the following equation for the combustion of octane (C8H18) , calculate the heat of reaction (enthalpy change) when 100.0 g of octane C8H18 reacts with oxygen in a combustion reaction. The molar mass of octane is 114.33 g/mole.
