P$1.$ Hydrogen is produced by the reaction:

$C{O}_{(g)}+H_2{O}_{(g)}longrightarrowC{O}_{2(g)}+H_{2(g)}$

The feed stream to the reactor is an equimolar mixture of carbon monoxide and steam,

and it enters the reactor at $398\mathrm{.}15K(125C)$ and atmospheric pressure. If $60\%$ of the

$H_{2}O$ is converted to $H_2$ and if the product stream leaves the reactor at $698\mathrm{.}15K({425}^{\text{'}\text{'}}C),$

how much heat must be transferred from the reactor?
