### reaction quotient

Can someone please explain how and when to use the reaction quotient and the difference between the reaction quotient and concentration?

The reaction quotient is calculated the same way as the equilibrium constant. If the reaction is at equilibrium, it is called K and if the reaction is not at equilibrium yet, it is called Q.

### Re: reaction quotient

When calculating the reaction quotient you are evaluating the reaction at some time that is not at equilibrium and you use the value to determine its relativity to reaching equilibrium. In the case where Q < K, there are more reactants compared to the reaction at equilibrium, therefore more products need to be created, hence the forward reaction is favored. Vice versa when Q > K, more products are present therefore reactants need to be made and the reverse reaction is favored.

Is the reaction quotient unit-less as well?

Yes the reaction quotient is unit-less
