### Quotient

Is Q basically the same thing as K or are they different?

Q itself, is the reaction quotient for the reaction given with whatever initial numbers that you are given. Whereas K is the equilibrium quotient, which is the ratio of the concentration/partial pressure of the products and reactants.

### Re: Quotient

Q is the reaction quotient, while K is the equilibrium quotient. They both follow the same expression -- the product of the concentrations or partial pressures of each product raised to the power of its stoichiometric coefficient over the product of the concentrations or partial pressures of each reactant raised to the power of its stoichiometric coefficient. However, when calculating Q, you can use the concentrations or partial pressures of the reactants and products at any point in the reaction. When calculating K, you use the equilibrium concentrations or partial pressures, not just any concentrations or partial pressures.
