Acetylene gas $($C$2$H$2)$ at $25\backslash$deg C is burned during a steady$-$flow combustion process with $30$ percent excess air at $27\backslash$deg C$.$ It is observed that $75,000$ kJ of heat is being lost from the combustion chamber to the surroundings per kmol of acetylene.Assuming combustion is complete, determine the general expression for adiabatic flame. Find the temperature of the exit gases
