The equation that relates the values of amounts of product and reactant at equilibrium is called
law of conservation of mass
Active mass
Law of mass action
none of these
Law of Mass Action -
“The rate at which a substance reacts is directly proportional to its active mass and rate of a chemical reaction is directly proportional to the product of active masses of reactants each raised to a power equal to corresponding stoichiometric coefficient appearing in the balanced chemical equation”.
rate of reaction ∝ [A]a.[B]b
rate of reaction = K[A]a[B]b
where K is the rate constant or velocity constant of the reaction at that temperature.
Therefore, option number (3) is correct.
