Hydrogen is burnt using $100\%$ excess air. Calculate the adiabatic flame temperature if the hydrogen is fed to the burner at $25C$ and the combustion air is at $75C.$

Data:

$C_p(O_2)$:$30J(molC{)}^{-1}$

$C_p(N_2)$:$30J(molC{)}^{-1}$

$C_p(H_{2}O)$:$35J(molC{)}^{-1}$

$H_c=-241\mathrm{.}84k\frac{J}{m}ol.$ This heat of combustion refers to each mole of fuel burnt at a datum temperature of $25C.$ The standard state of reactants and products are gases. Air consists of a mixture of $79\%$ nitrogen and $21\%$ oxygen on a volume basis.
