If liquid $n-$heptane $(C_7{H}_{16})$ with a heat of formation of $-224\mathrm{.}4kJ/$kmol reacts with air, determine the adiabatic flame temperature when $40\%$ excess air is used. Use the $C_p$ data with only two constants $)=(a+bT$ found in the appendices of the $$engel$-$Boles text. Give the molar amounts needed for the gaseous products based on one mole of $n-$heptane.
