# Problem: Consider the following reaction: CO(g) + 2 H2(g) ⇌ CH3OH(g)An equilibrium mixture of this reaction at a certain temperature was found to have [CO] = 0.110 M , [H2]= 0.114 M , and [CH3OH] = 0.190 M. What is the value of the equilibrium constant (Kc) at this temperature?

###### FREE Expert Solution

We’re being asked to determine the equilibrium constant for this reaction:

CO(g) + 2 H2(g) ⇌ CH3OH(g)

Recall that the equilibrium constant is the ratio of the products and reactants

We use Kp when dealing with pressure and Kc when dealing with concentration:

$\overline{){{\mathbf{K}}}_{{\mathbf{p}}}{\mathbf{=}}\frac{{\mathbf{P}}_{\mathbf{products}}}{{\mathbf{P}}_{\mathbf{reactants}}}}$     $\overline{){{\mathbf{K}}}_{{\mathbf{c}}}{\mathbf{=}}\frac{\mathbf{\left[}\mathbf{products}\mathbf{\right]}}{\mathbf{\left[}\mathbf{reactants}\mathbf{\right]}}}$

Note that solid and liquid compounds are ignored in the equilibrium expression.
