$13\mathrm{.}25$ gaseous acetylene $($c$2$h$2)$ enters a stationary reactor at $25\backslash$deg c and $1\mathrm{.}6$ bar and burns completely with $150\%$ of the theoretical air entering under the same conditions. if the products leave at $25\backslash$deg c and $1\mathrm{.}5$ bar, calculate the heat transferred from the reactor, in kj per kmol of fuel. the effects of kinetic and potential energies are neglected.
