Question

Answer

Law of mass action states that the rate of reaction is proportional to the product of molar concentration of reactant with each concentration term raised to power its stoichiometric coefficient.

Answer

Mass action

Answer

The law of mass action states that the rate of a chemical reaction is directly proportional to the product of the molar concentration of the reactants raised to their stoichiometric coefficient.

Answer

The Law of Mass Action is a fundamental principle of chemical kinetics that describes the relationship between the rate of a chemical reaction and the concentrations of the reactants involved. According to this law, the rate of a chemical reaction is directly proportional to the product of the molar concentrations of the reactants, with each concentration term raised to the power of its stoichiometric coefficient.

Explanation:

The Law of Mass Action can be mathematically expressed as follows:

Rate of reaction = k [A]^m [B]^n

Where:

k = rate constant
[A] = molar concentration of reactant A
[B] = molar concentration of reactant B
m and n = stoichiometric coefficients of reactant A and B, respectively

The law states that the rate of a chemical reaction is proportional to the product of the concentrations of the reactants, with each concentration term raised to the power of its stoichiometric coefficient. This means that the higher the concentration of the reactants, the faster the reaction will proceed.

The Law of Mass Action is based on the concept of chemical equilibrium, which is the state in which the rates of the forward and reverse reactions are equal. At equilibrium, the concentrations of the reactants and products remain constant, and the reaction proceeds at a constant rate. The law can be used to predict how changes in the concentrations of the reactants will affect the rate of the reaction.

Applications:

The Law of Mass Action has many applications in chemistry, including:

- Determining the rate of a chemical reaction: The law can be used to calculate the rate of a chemical reaction based on the concentrations of the reactants.
- Predicting the effect of concentration changes: The law can be used to predict how changes in the concentrations of the reactants will affect the rate of the reaction.
- Understanding chemical equilibrium: The law is based on the concept of chemical equilibrium, which is the state in which the rates of the forward and reverse reactions are equal.
