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.
What units must the rate constant have based on the rate law, and can you provide an example of how to calculate it?
The rate constant must have units that make the rate equation balanced. For example, if the rate law is rate kA2B, the rate constant k must have units of M-2 s-1. To calculate the rate constant, you can use experimental data and the rate law equation to solve for k.
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.
Which of these mechanisms is consistent with the rate law?
The mechanism that is consistent with the rate law is the one that matches the experimentally determined rate equation.
What must be known for the rate constant to be calculated from the rate law?
The reaction rate at known reactant concentrations.
How can rate constant be determined from the rate law?
The rate constant is the reaction rate divided by the concentration terms.

How can rate constants be determined from the rate law?
You need to know the rate of the reaction, as well as the concentrations of all reactants. Then you plug those values into the equation of rate = k[A][B] or whatever the rate equation happens to be.
How can the rate constant be determine from the rate law?
The rate constant is the reaction rate divided by the concentration terms.
Specific rate constant?
specific rate constant is an experimentally determined proportionality constant which is different for different reactions and changes only with temperature.
Define a specific rate constant?
The specific rate constant a proportionally determined constant that is usually different for various reactions with changes in temperature.
What units must the rate constant have based on the rate law, and can you provide an example of how to calculate it?
The rate constant must have units that make the rate equation balanced. For example, if the rate law is rate kA2B, the rate constant k must have units of M-2 s-1. To calculate the rate constant, you can use experimental data and the rate law equation to solve for k.
What is the k in the rate law equation?
A rate constant

The reaction rate at known reactant concentrations.
What is the value and unit of the rate constant for this reaction?
The value and unit of the rate constant for a reaction represent how fast the reaction occurs. The rate constant is typically denoted by the symbol "k" and its unit depends on the overall order of the reaction. The unit of the rate constant can be determined by the reaction rate equation.
