### Q

When is Q used and what's the difference between it and K?

### Re: Q

K and Q are really similar when it comes to solving for them (they use the same formulas). Q however, can be solved during any point of a reaction, while K is only solved for at equilibrium.

### Re: Q

Q is the ratio between products and reactants that is found when the reaction has not yet reached equilibrium. K is the ratio when the reaction is already at equilibrium. Therefore, we can use Q to see which way the reaction will proceed.

### Re: Q

Q is used to determine whether the reaction is at equilibrium or not. The equation for Q is the same equation as the one for K. We compare Q to K to determine which way the reaction is shifted.

### Re: Q

Q is the reaction quotient and is calculated at any time during a reaction. Q will change as time passes. Q and K are similar except that K is the value when the reaction is at equilibrium. If Q>K, the reverse reaction is favored, and if Q<K, the forward reaction is favored. IF Q=K, the both reverse and forward are occurring at the same rate.

### Re: Q

for example, when K>Q, then the reaction shifts to the right

### Re: Q

Q and K are solved in the same way, however, K is the equilibrium constant by definition, while Q is the reaction quotient which can be found at any point in the reaction timeline, and based on whether Q is less than, greater than, or equal to K predictions about the reactions future can be made.
