/kloc-mid-0/9th century, G.M. Goldberg and

Wagner put forward that the chemical reaction page is directly proportional to the effective mass of reactants. This is the law of mass action, in which the effective mass actually refers to the concentration. Modern experiments have proved that the law of mass action is only applicable to meta-reactions.

[ 1]

Therefore, the law can be more strictly and completely expressed as: the reaction rate of the meta-reaction is directly proportional to the product of the power of each reactant concentration, where the exponent of the power of each reactant concentration is the absolute value of the stoichiometric number of reactants in the meta-reaction equation. For example, for binary reaction I2+H2 → 2hi, the rate equation can be written according to the law of mass action:

r=ki2

deuterium

Where r is the reaction rate, [i2] and h2 are the concentrations of reactants i2 and h2, respectively, and k is called the reaction rate constant. According to the law of mass action, the order of elementary reaction is equal to the number of molecules.
