Define Rate law ☺☺

​

Answer 1

Here's your answer

The rate law or rate equation for a chemical reaction is an equation that links the reaction rate with the concentrations or pressures of the reactants and constant parameters (normally rate coefficients and partial reaction orders).[1] For many reactions the rate is given by a power law such as

r

=

k

[

A

]

x

[

B

]

y

r\;=\;k[{\mathrm {A}}]^{x}[{\mathrm {B}}]^{y}

where [A] and [B] express the concentration of the species A and B (usually in moles per liter (molarity, M)). The exponents x and y are the partial orders of reaction for A and B and the overall reaction order is the sum of the exponents. These are often positive integers, but they may also be zero, fractional, or negative. The constant k is the reaction rate constant or rate coefficient of the reaction. Its value may depend on conditions such as temperature, ionic strength, surface area of an adsorbent, or light irradiation.

Answer 2

Answer:

The rate law is a mathematical relationship obtained by comparing reaction rates with reactant concentrations. The reaction order is the sum of the concentration term exponents in a rate law equation. A reaction's rate law may be determined by the initial rates method.

In general, a rate law (or differential rate law, as it is sometimes called) takes this form: in which [A], [B], and [C] represent the molar concentrations of reactants, and k is the rate constant, which is specific for a particular reaction at a particular temperature.

In general, the rate law can calculate the rate of reaction from known concentrations for reactants and derive an equation that expresses a reactant as a function of time.......
