I am having trouble with a question on my lab report that is as follows:

"Calculate the number of moles of reactants and products in an equilibrium mixture. Complete the ICE table below."

I am given the Keq which is 3 and the initial amount of acid and alcohol which are (0.25/V) each.

If anyone could help me start this question or give me a link on a good website to find out how to do it it would be much appreciated!

Thank you in advance!
