Is it a chemical equilibrium?
A mixture contains methane acid with a concentration of 3.9 mol, methanol with a concentration of 5.8 mol, water with a concentration of 7.7 mol, and methane acid methyl ester with a concentration of 7.7 mol. The equilibrium constant is 3.9. Explain whether the mixture is in chemical equilibrium.

Hi.
Your starting materials are methane acid and methanol, your products are methyl methane and water.
For the equilibrium constant:
K = [c(HCOOCH3)•c(H2O)]/[c(H3COH)•c(HCOOH)]
= [7.7 mol/L]2 / [5.8 mol/L • 3.9 mol/L]
= 2.62
Since the equilibrium constant in equilibrium is 3.9, but here we get 2.62 as a result, the system is not in equilibrium at this time.

Thank you!
You're welcome.
Well, just guess that. Use the given concentrations into the MWG and see if the given value for K is found.
What is an MWG?
Mass law. More precisely, mass effect quotient.
