$(30$ points$)$ The water$-$gas shift reaction is carried out isothermally in a flow reactor with no pressure

drop.

$CO(g)+H_{2}O(g)C{O}_2(g)+H_2(g)$

Initial feed is composed of carbon monoxide, water, hydrogen, and nitrogen $($inert$).$ The partial

pressure of initial feed is shown below.

$P_{CO}^0=0\mathrm{.}12$atm,$P_{H_{2}O}^0=0\mathrm{.}38$atm,$P_{H_2}^0=0\mathrm{.}38$atm,$P_{N_2}^0=0\mathrm{.}54$atm

At the reaction temperature of $503K,$ determine the following.

$(1)(7$ pts$)$ Construct a stoichiometric table of water$-$gas shift reaction with the given information.

$(2)(8$ pts$)$ The rate law of water$-$gas shift reaction can be expressed by the following Langmuir$-$

Hinshelwood kinetics.

$-r_{CO}=\frac{k(P_{CO}{P}_{H_{2}O}-\frac{P_{C{O}_2}{P}_{H_2}}{K_{eq}})}{(1+K_{CO}{P}_{CO}+K_{H_{2}O}{P}_{H_{2}O}+K_{C{O}_2}{P}_{C{O}_2}+K_{H_2}{P}_{H_2}{)}^2}$
