Both the $[CO]$ and $[CO_2]$ will increase

(D) Solution:- $(D)$ Both the $[CO]$ and $[CO_2]$ will increase.For the reaction:$H_2O_{(g)} + CO_{(g)} \rightleftharpoons H_{2(g)} + CO_{2(g)} + \text{Heat}$When the volume of the reaction vessel is decreased,the pressure increases.According to the definition of concentration,$C = \frac{n}{V}$.Since the volume $V$ decreases,the concentration of all gaseous species present in the vessel (both reactants and products) increases immediately.Therefore,both $[CO]$ and $[CO_2]$ will increase.

Mix Examples- 6-1.Equilibrium (Chemical Equilibrium)

$N_2O_{4(g)}$ at $300 \ K$ is kept in a closed container under $1 \ atm$. At equilibrium,$20\%$ of $N_2O_{4(g)}$ is converted to $NO_{2(g)}$.
$N_2O_{4(g)} \rightleftharpoons 2NO_{2(g)}$
Hence,the resultant pressure is: (in $atm$)
