### Kc and shifting of reaction

When given Kc how do you determine which way the reaction would shift based on this value?

I think if you are given Q with Kc, then you can see how the reaction will shift. If Q<K, the reaction shifts right. If Q>K, the reaction shifts left.

With just Kc, you can only determine if the reaction favors the products or reactants. You need to find Q in order to see which direction the reaction will shift.

### Re: Kc and shifting of reaction

If you are given all the initial concentrations, the first thing you should do is calculate Q by plugging it into the (Products)/(Reactants Formula) in order to determine the shift. If you don't, you might get the wrong signs for X in your ICE table.
