Question

what is rate constant law. explain​

Answer 1

Answer:

rate constant explains the relationship between the molar concentration of the reactants and the rate of a chemical reaction. The rate constant is denoted by k and is also known as reaction rate constant or reaction rate coefficient.

Answer 2

Rate constant law:

• A  rate law is an expression showing the relationship of the reaction rate to the concentrations of each reactant. The specific rate constant (K) is the proportionality constant relating the rate of the reaction to the concentration of reactants.

• In chemical kinetics, a reaction rate constant or reaction rate coefficient quantifies the rate and direction of a chemical reaction. For a reaction between reactant A and B to form products C.

                               aA +bB→ cC

            the reaction rate is often found to have the form;

                           r =k(T)[A]m[B]n

• K(T) is the reaction rate constant that depends on the temperature, and [A] and [B] are the molar concentrations of substances A and B in moles per unit volume of solution.

• The exponents m and n are called partial orders of reaction and not are generally equal to the stoichiometric coefficients a and b.

• The value of the rate constant is temperature-dependent. A large value of the rate constant means that the reaction is relatively fast, while a small value of the rate constant means that the reaction is relatively slow.
