Question

Write a balanced chemical equation for the reaction whose KC expression is as: KC = [ CH3OH ] 1 [CO] [H2]2

Answer 1

CH3OH--->CO+2H2O..........

Answer 2

Answer: The reaction for the given equilibrium constant expression is given below.

Explanation:

Equilibrium constant is the ratio of concentration of the products to the concentration of the reactants each raised to the power their respective stoichiometric coefficients.

We are given an expression for the equilibrium concentration constant, which is:

$K_c=\frac{[CH_3OH]^1}{[CO][H_2]^2}$

From the expression, we can say that the reactants are Co and $H_2$ and product is $CH_3OH$. So, the reaction follows:

$CO+2H_2\rightarrow CH_3OH$

By Stoichiometry of the reaction:

1 mole of carbon monoxide reacts with 2 moles of hydrogen gas to produce 1 mole of methanol.
