A$)$Consider the following equilibrium:

$CO(g)+H_{2}O(g)C{O}_2(g)+H_2(g),K_{eq}=4\mathrm{.}6$

Initially, $0\mathrm{.}50$molCO,$0\mathrm{.}50mol{H}_{2}O,0\mathrm{.}62molC{O}_2$ and $0\mathrm{.}62mol{H}_2$ are placed in a $1\mathrm{.}0L$ container, and the reaction proceeds towards products.

Calculate the equilibrium $H_2.$

B$)$consider the equilibrium: $C{O}_2(g)+H_2(g)CO(g)+H_{2}O(g),K_{eg}=1\mathrm{.}60$

Initially, $8\mathrm{.}2$mol of $CO$ and $8\mathrm{.}2$mol of $H_{2}O$ are placed in a $2\mathrm{.}0L$ contaner and allowed to react. Calculate the equilibrium concentrations of $C{O}_2$ and $CO.$
