Answer 1

Answer:

Explanation:

In chemical kinetics a reaction rate constant or reaction rate coefficient, k, quantifies the rate of a chemical reaction.[1]

For a reaction between reactants A and B to form product C

a A + b B → c C

the reaction rate is often found to have the form:

{\displaystyle r=k(T)[\mathrm {A} ]^{m}[\mathrm {B} ]^{n}}{\displaystyle r=k(T)[\mathrm {A} ]^{m}[\mathrm {B} ]^{n}}

Here k(T) is the reaction rate constant that depends on temperature, and [A] and [B] are the molar concentrations of substances A and B in moles per unit volume of solution, assuming the reaction is taking place throughout the volume of the solution. (For a reaction taking place at a boundary one would use instead moles of A or B per unit area.)

The exponents m and n are called partial orders of reaction and are not generally equal to the stoichiometric coefficients a and b. Instead they depend on the reaction mechanism and can be determined experimentally.
