Question

Rate law equation The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction between AA and BB, aA+bB⇌cC+dD aA+bB⇌cC+dD The dependence of the reaction rate on the concentration of each reactant is given by the equation called the rate law: rate=k[A]m[B]rate=k[A]m[B]n where kkk is a proportionality constant called the rate constant. The exponent mmm determines the reaction order with respect to AA, and nnn determines the reaction order with respect to BB. The overall reaction order equals the sum of the exponents (m+nm+n).

Answer 1

The rate law represents how the reaction rate relates to reactant concentrations, where k is the rate constant and m and n are the reaction orders determined experimentally.

Step-by-step explanation:

The rate law of a reaction is a fundamental concept in chemical kinetics that explains how the reaction rate is related to the concentrations of reactants. It is given by the equation rate = k[A]m[B]n, where k represents the rate constant and the exponents m and n indicate the reaction order with respect to each reactant. These reaction orders must be determined through experiments, as they don't necessarily correlate with the stoichiometric coefficients in a balanced chemical equation. The overall reaction order is the sum of these exponents, and the rate constant k is specific to the reaction conditions such as temperature and pressure and remains constant throughout the reaction under a given set of conditions.

Answer 2

Step-by-step explanation:

In the following reaction;

aA+bB⇌cC+dD

A and B are the reactants while C and D are the products.

a, b, c and d are regarded as coefficients.

The dependence of the reaction on the concentration of the reactants is given by the rate law.

This is given by;

rate= k [A]^m [B]^n

where

K = Rate constant. Constant for the reaction at that temperature.

m = order of reeaction with respect to A

n = order of reaction with repsect to B

Overall order of reaction is given by m + n
