Q vs K

[705984992]

Why does the reaction quotient change when it approaches equilibrium and how does it relate back to K?

[806018033]

As a reaction approaches equilibrium, the concentrations of reactants and products change, altering the reaction quotient (Q). At equilibrium, Q reaches its equilibrium constant (K), indicating that the rate of the forward and reverse reactions are equal and the concentrations of reactants and products stabilize.

Reaction quotient is a measure of the concentrations of reactants and products at a given time in a reaction. As a reaction reaches equilibrium, the reaction quotient gets closer to K, the equilibrium constant. When Q > K, there are more products than reactants. When Q < K, there are more reactants than products.
