Re: Q
Q is written the same way as K is. Q=[products]/[reactants] and both solids and liquids are excluded from the expression.

Re: Q
To find Q, or the reaction quotient, you would need to use the same equation used to find K, or the equilibrium constant. Also only include gases and aqueous phases in your equation to find Q.

Re: Q
How did you get 1 in the numerator? I know that the molar concentration of a pure substance (solid or liquid) does not change in a reaction so they are not included, but where did you get the 1 from?

Re: Q
Can someone explain what exactly Q is? I know that it is the reactant quotient but I don't get why Q and K wouldn't always equal each other if they have the same formula [P]/[R]?

Re: Q
Q and K are not always the same because Q represents [P]/[R] at any time in the reaction while K represents that ratio only when the reaction is at equilibrium. If Q does not equal K, we know that the equation is not at equilibrium.
