Acetylene gas $($C$2$H$2)$ at $25\backslash$deg C$,1$atm enters an insulated reactor operating at steady state and burns completely with $130\%$ theoretical air entering at $25\backslash$deg C$,1$atm. Assume air has a molar analysis of $21\%$O$2$ and $79\%$N$2.$ Determine the adiabatic flame temperature, in K
