What is the rate of a reaction that follows the rate law rate kAmBn if k 02 A and B are each 3 M m 2 and n3?
To determine the rate of the reaction that follows the rate law rate = k[A]^m[B]^n, where k = 3 M^(-2) s^(-1), [A] = 2 M, and [B] = 3 M, we first need to substitute these values into the rate law. Given that m = 2 and n = 3, the rate can be calculated as follows: Rate = k[A]^m[B]^n = 3 M^(-2) s^(-1) * (2 M)^2 * (3 M)^3 = 3 * 4 * 27 = 324 M/s. Thus, the rate of the reaction is 324 M/s.
How does the rate law show how concentration changes affet the rate of reaction?
The rate law expresses the relationship between the rate of a chemical reaction and the concentrations of the reactants. It is typically formulated as Rate = k[A]^m[B]^n, where k is the rate constant, and m and n are the reaction orders for reactants A and B, respectively. The exponents indicate how the rate is affected by changes in concentration; for example, if m = 1, doubling the concentration of A will double the reaction rate, whereas if m = 2, the rate will quadruple. Thus, the rate law quantitatively illustrates how variations in reactant concentrations influence the overall reaction rate.
What is the rate of a reaction that follows the rate law rate kAmBn if k 0.02 A and B are each 3 M m 1and n 2?
To find the rate of the reaction, we can use the given rate law: ( \text{rate} = k[A]^m[B]^n ). Substituting the values, we have ( k = 0.02 , \text{M}^{-1}\text{s}^{-1} ), ( [A] = 3 , \text{M} ), and ( [B] = 3 , \text{M} ) with ( m = 1 ) and ( n = 2 ). Thus, the rate is calculated as: [ \text{rate} = 0.02 \times (3)^1 \times (3)^2 = 0.02 \times 3 \times 9 = 0.54 , \text{M/s} ] Therefore, the rate of the reaction is 0.54 M/s.
How can the rate constant be determined form the rate law?
The rate constant can be determined from the rate law by rearranging the rate equation to isolate the constant. For a reaction with a rate law of the form ( \text{Rate} = k[A]^m[B]^n ), where ( k ) is the rate constant, ( [A] ) and ( [B] ) are the concentrations of the reactants, and ( m ) and ( n ) are their respective orders, one can measure the reaction rate at known concentrations. By substituting these values into the rate law and solving for ( k ), the rate constant can be calculated. This process often involves experimental data collected under controlled conditions.
How does the rate law show his concentration changes affect the rate of reaction?
The rate law expresses the relationship between the rate of a chemical reaction and the concentrations of the reactants. It is typically formulated as Rate = k[A]^m[B]^n, where k is the rate constant, [A] and [B] are the concentrations of the reactants, and m and n are the reaction orders which indicate how the rate changes with concentration. If the concentration of a reactant increases, the rate of reaction will typically increase as well, depending on its exponent in the rate law, reflecting the dependency of reaction kinetics on reactant concentrations. Thus, the rate law quantitatively describes how variations in concentration influence the speed of the reaction.
