q vs k

Postby connie 2C » Mon Jan 20, 2020 12:27 am

will the q value eventually reach k? is q the value that is calculated when the reaction is not at equilibrium?

Yes Q is the value calculated when the reaction is not at equilibrium.

Q is the reaction quotient and expresses the relative ratio of products to reactants at a given instant. On the other hand, K is the equilibrium constant and is used to calculate the final concentrations at equilibrium for a reaction using an ICE table. If Q and K equal each other, the reaction is at equilibrium.

When Q reaches K, it is at equilibrium.

Yes if a reaction reaches equilibrium, it will have Q=K

Yes, when Q=K the solution has reached its equilibrium composition and doesn't change in either direction.

Yes Q is just the value of equilibrium at any given point and K is the equilibrium constant. When Q and K are equal, that would show you that the reaction is at equilibrium.

Q value is calculated when you don't know whether the reaction is at equilibrium or not. If Q equals K, then the reaction is at equilibrium.

The q value will eventually reach k given a long period of time, because that's where the reaction occurs at equilibrium.

Q represents the current state of the system but K is the equilibrium state. Eventually, Q will go towards K.
