Consider the following chemical reaction: co (g) + 2h2(g) ↔ ch3oh(g) at equilibrium in a particular experiment, the concentrations of co and h2 were 0.15 m and0.36 m, respectively. what is the equilibrium concentration of ch3oh? the value of keq for this reaction is 14.5 at the temperature of the experiment.

The equilibrium concentration of CH₃OH is 0.28 M

Explanation:

For the reaction: CO (g) + 2H₂(g) ↔ CH₃OH(g)

The equilibrium constant (Keq) is given for the following expresion:

Keq= =14.5

Where (CH3OH), (CO) and (H2) are the molar concentrations of each product or reactant.

We have:

(CH3OH)= ?

(CO)= 0.15 M

(H2)= 0.36 M

So, we only have to replace the concentrations in the equilibrium constant expression to obtain the missing concentration we need:

14.5=

14.5 x (0.15 M) x = (CH₃OH)

0.2818 M = (CH₃OH)
