Question

construct the expression for kc for the following reaction.
co(g) + 2 h₂(g) ⇌ ch₃oh(g)
drag the tiles into the numerator or denominator to form the expression. each reaction participant must be represented by one tile. do not combine terms.
kc =

Explanation:

Step1: Recall equilibrium - constant expression

For a general reaction $aA + bB
ightleftharpoons cC + dD$, the equilibrium - constant expression $K_c=\frac{[C]^c[D]^d}{[A]^a[B]^b}$, where $[X]$ is the molar concentration of species $X$ and $a,b,c,d$ are the stoichiometric coefficients.

Step2: Identify reactants and products and their coefficients

For the reaction $CO(g)+2H_2(g)
ightleftharpoons CH_3OH(g)$, the products are $CH_3OH$ with a coefficient of 1, and the reactants are $CO$ with a coefficient of 1 and $H_2$ with a coefficient of 2.

Step3: Write the $K_c$ expression

$K_c=\frac{[CH_3OH]}{[CO][H_2]^2}$

Answer:

$K_c=\frac{[CH_3OH]}{[CO][H_2]^2}$
