Ammonia is oxidized with air to form nitric oxide in the first step of the production of nitric acid. Two principal gas$-$phase reactions

occur:

$4N{H}_3+5O_{2}4NO+6H_{2}O$

$2N{H}_3+1\mathrm{.}5O_2{N}_2+3H_{2}O$

All species in the following flowchart are gases.

Physical Property Tables

Taking elemental species $N_2((g)),H_2((g)),O_2((g))$ at $25C$ as references, prepare and fill in an inlet$-$outlet enthalpy table.

Calculate the required rate of heat transfer to or from the reactor in $kW.$

The magnitude of the heat transfer is
