Consider the combustion of 1 kmol of propane with air at 1 atm. construct a single graph using h-t coordinates that shows the following: a. reactants' enthalpy, h, in kj versus temperature, over the range of 298–800 k for o = 1.0. b. repeat part a for =0.75. repeat part a for q = 1.25. d. products' enthalpy, h, for ideal combustion (no dissociation) versus temperature, over the range of 298–3500 k for 0 = 1.0. e. repeat part d for q = 0.75. f. repeat part d for ø = 1.25, using the water-gas equilibrium to ac- count for incomplete combustion.
