This reaction was monitored as a function of time: AB → A + B A plot of 1/[AB] versus time yields a straight line with a slope of +0.25/Ms. b. Write the rate law for the reaction.

검증된 단계별 안내
1
Identify the order of the reaction by analyzing the plot. A plot of 1/[AB] versus time that yields a straight line indicates a second-order reaction.
For a second-order reaction, the rate law is expressed as: rate = k[AB]^2.
The slope of the plot of 1/[AB] versus time is equal to the rate constant k for a second-order reaction.
Given that the slope is +0.25/Ms, this value represents the rate constant k.
Therefore, the rate law for the reaction is: rate = 0.25 [AB]^2.

Rate Law

The rate law expresses the relationship between the rate of a chemical reaction and the concentration of its reactants. It is typically formulated as rate = k[A]^m[B]^n, where k is the rate constant, and m and n are the orders of the reaction with respect to each reactant. Understanding the rate law is essential for predicting how changes in concentration affect the reaction rate.

Rate Law Fundamentals

Order of Reaction

The order of a reaction refers to the power to which the concentration of a reactant is raised in the rate law. It indicates how the rate is affected by the concentration of that reactant. For example, if the order is 1, doubling the concentration will double the rate; if it is 2, doubling the concentration will quadruple the rate. The overall order is the sum of the individual orders.

Integrated Rate Laws

Integrated rate laws relate the concentration of reactants to time, allowing for the determination of reaction order from experimental data. For a second-order reaction, the integrated form is 1/[AB] = kt + 1/[AB]0, where [AB]0 is the initial concentration. The linear relationship observed in the plot of 1/[AB] versus time indicates that the reaction is second-order with respect to AB, which is crucial for writing the correct rate law.
