What is the zero order reaction rate law and how does it determine the rate of a chemical reaction?
The zero order reaction rate law states that the rate of a chemical reaction is independent of the concentration of the reactants. This means that the rate of the reaction remains constant over time. The rate of the reaction is determined solely by the rate constant, which is specific to each reaction. This rate law is expressed as: Rate k, where k is the rate constant.

How do coefficients affect the rate law of a chemical reaction?
Coefficients in a chemical reaction affect the rate law by determining the order of the reaction with respect to each reactant. The coefficients indicate how many molecules of each reactant are involved in the reaction, which helps determine the overall rate of the reaction.
How can one determine the rate law from elementary steps in a chemical reaction?
To determine the rate law from elementary steps in a chemical reaction, you need to examine the slowest step, also known as the rate-determining step. The coefficients of the reactants in this step will give you the order of the reaction with respect to each reactant. The rate law can then be determined by combining the orders of the reactants from the rate-determining step.
How can one determine the order of a reaction from a table?
To determine the order of a reaction from a table, you can look at how the rate of the reaction changes with the concentration of reactants. If doubling the concentration of a reactant doubles the rate, the reaction is first order with respect to that reactant. If doubling the concentration quadruples the rate, the reaction is second order. And if doubling the concentration increases the rate by a factor of eight, the reaction is third order.
How can one determine the order of reaction from a given table of data?
To determine the order of reaction from a given table of data, you can look at how the rate of the reaction changes with the concentration of the reactants. If the rate is directly proportional to the concentration of a reactant, the reaction is first order with respect to that reactant. If the rate is proportional to the square of the concentration, the reaction is second order. By analyzing the data and observing how the rate changes with different concentrations, you can determine the order of the reaction.
How can one effectively write a rate law for a chemical reaction?
To write a rate law for a chemical reaction, one must determine the order of the reaction with respect to each reactant by conducting experiments and analyzing the rate of reaction at different concentrations. The rate law is then expressed as rate kAmBn, where k is the rate constant, A and B are the concentrations of the reactants, and m and n are the orders of the reaction with respect to each reactant.
How can one determine the rate constant for a second-order reaction?
To determine the rate constant for a second-order reaction, one can use the integrated rate law for a second-order reaction, which is: 1/At kt 1/A0. By plotting 1/At against time and finding the slope, which is equal to the rate constant k, one can determine the rate constant for the second-order reaction.
How can one determine the rate constant in a chemical reaction?
The rate constant in a chemical reaction can be determined by conducting experiments and measuring the reaction rate at different concentrations of reactants. By plotting the data and using the rate equation, the rate constant can be calculated.
