H2(g) + CO2(g) + 10 kcal H2O(g) + CO(g)
EleoNora [17]

<u>Answer:</u> The equilibrium constant for the given reaction is 0.8

<u>Explanation:</u>

Equilibrium constant is defined as the ratio of concentration of the products raised to the power its stoichiometric coefficients to the concentration of reactants raised to power its stoichiometric coefficient. It is represented as K_c

For the general equation:

aA+bB\rightleftharpoons cC+dD

The equilibrium constant is represented as:

K_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}

For the given chemical equation:

H_2(g)+CO_2(g)+10 kcal\rightleftharpoons H_2O(g)+CO(g)

K_c for this equation is given by:

K_c=\frac{[H_2O][CO]}{[H_2][CO_2]}

Concentration at equilibrium of

H_2=2mol/L\\H_2O=4mol/L\\CO_2=5mol/L\\CO=4mol/L

Putting values in above equation, we get:

K_c=\frac{4\times 4}{2\times 5}\\K_c=0.8

Hence, the equilibrium constant for the given chemical reaction is 0.8
