Difference betwen constant and quotient?

[welcometochillis]

They follow a similar formula and are both dependent on the ratio of the molecules in the reaction, what is the main difference between the two? Is the quotient simply when the rxn is not in equilibrium???

Yes the reaction quotient is different only because the reaction is not at equilibrium.
But Q and Qsub(c) and Qsub(p) are all calculated the same way as k.

[StephanieRusnak]

they're the same just different notation for when it's not at equilibrium

We need to compare the equilibrium constant and the reaction quotient in order to figure out the direction a reaction is going.

They are calculated the same way, but the quotient represents the reaction at any time while the constant is only when the reaction is at equilibrium
