basic concepts of chemical equilibrium

Question 1

what is chemical equilibrium?

Answer 1

• chemical equilibrium is a state in a reversible reaction where the rate of the forward reaction equals the rate of the reverse reaction.
• the concentrations of reactants and products remain constant.

Question 2

what is the equilibrium constant (k)?

Answer 2

• the equilibrium constant (k) is a number that expresses the ratio of the concentrations of products to reactants at equilibrium.
• each raised to the power of their stoichiometric coefficients.
