ICE Table "Change" Row

[Namita Shyam 3G]

In the "Change" row of the ICE table, how do we figure out whether products or reactants will increase? Do we always need to find Q and compare it with K to figure out if the reaction will form products or not? For example, if the initial concentration of one product and one reactant is given, how do we know whether products or reactants increase?

Hello! I think one way we would not have to compare Q and K is when no product is made at all yet/ the reaction is just beginning, which would mean that the products will increase. However, I do think you are correct in that if we already have a certain amount of reactant and product, we need to compare if the solution is at equilibrium or not first (if Q=K or not). I hope this helps!

That makes sense! Thank you!!
