What is the k in the rate law equation?
A rate constant
How can the rate 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.
Which equation would be used to calculate the rate constant from inital concentrations?
To calculate the rate constant (k) from initial concentrations, you would typically use the rate law equation for the reaction, which is expressed as ( \text{Rate} = k[A]^m[B]^n ), where ( [A] ) and ( [B] ) are the initial concentrations of the reactants, and ( m ) and ( n ) are their respective reaction orders. By measuring the initial rate of the reaction and substituting the initial concentrations into the rate law, you can rearrange the equation to solve for the rate constant ( k ).

How can the rate constant be determined fro the rate law?
The rate constant can be determined from the rate law by rearranging the rate equation to isolate the rate constant (k). Typically, the rate law is expressed as ( \text{Rate} = k [A]^m [B]^n ), where ( [A] ) and ( [B] ) are the concentrations of reactants and ( m ) and ( n ) are their respective reaction orders. By measuring the reaction rate at known concentrations of the reactants, you can calculate k using the formula ( k = \frac{\text{Rate}}{[A]^m [B]^n} ). This requires experimental data to provide the necessary values for rate and concentrations.
Which equation is an expression of the rate law?
Rate = k[A]m[B]n
What is the k in the rate law equation?
A 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.
What is the zero order rate law equation and how does it relate to the rate of a chemical reaction?
The zero-order rate law equation is Rate k, where k is the rate constant. In a zero-order reaction, the rate of the reaction is independent of the concentration of the reactants. This means that the rate of the reaction remains constant over time, regardless of changes in reactant concentrations.

What equation shows how rate depends on concentrations of reactions?
The equation is called the rate law equation. For the reaction aA+bB =>cC+dD the rate law would be rate = k[A]^m[B]^n where k is the rate constant and m and n are the "order" with respect to each reactant. m and n must be determined experimentally and may or may not be the same as the coefficients a and b.

To calculate the rate constant (k) from initial concentrations, you would typically use the rate law equation for the reaction, which is expressed as ( \text{Rate} = k[A]^m[B]^n ), where ( [A] ) and ( [B] ) are the initial concentrations of the reactants, and ( m ) and ( n ) are their respective reaction orders. By measuring the initial rate of the reaction and substituting the initial concentrations into the rate law, you can rearrange the equation to solve for the rate constant ( k ).

What is necessary to determine the rate of a reaction using the rate law?
To determine the rate of a reaction using the rate law, you need to know the rate constant (k), the concentrations of the reactants, and the order of the reaction with respect to each reactant. The rate law equation relates the rate of the reaction to these factors.
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.
What is the rate of a reaction that follows the rate law rate kAmBn where k 0.2 A3 M B3 M m1 n2?
The rate of the reaction can be calculated using the rate law equation rate = k[A]^m[B]^n. Plugging in the given values k = 0.2, m = 1, n = 2, [A] = 3 M, and [B] = 3 M into the equation gives rate = 0.2 * (3)^1 * (3)^2 = 16.2 M/s.
What would happen to the rate of a reaction with rate law rate kno2h3 if the concentration of no were doubled?
If the concentration of NO was doubled in the rate law rate = k[NO]2[H3], the rate of the reaction would increase by a factor of 4. This is because the rate of a reaction typically increases with an increase in the concentration of reactants, raised to a power dictated by their respective coefficients in the rate law equation.
