According to Charles's law for a fixed quantity of gas at constant pressure which of the given quantities is constant?
In Charles' Law, the mass is held constant which means that the pressure on the gas is constant.
What has the largest value of the constant k?
how does the rate law show how concentration changes after the rate of reaction
Find a formula for Poiseuilles Law given that the rate of flow is proportional to the fourth power of the radius and Use k as the proportionality constant?
Rate of flow varies as R^4 where R is the radius or Rate of flow = (k) x (R^4)
What is meant by the law of constant composition for compounds?
The law of constant composition for compounds is a law in chemistry according to which any given compound always contains the same component elements in the same ratios, by mass. The ratios do not depend on where the compound comes from or the way in which it was produced.
What is formula of rate constant?
The rate constant, often denoted as ( k ), is a proportionality factor in the rate law of a chemical reaction. Its formula depends on the order of the reaction. For a first-order reaction, ( k ) has units of ( s^{-1} ), while for a second-order reaction, it has units of ( M^{-1}s^{-1} ). The general expression for the rate law can be represented as ( \text{Rate} = k[A]^n ), where ( [A] ) is the concentration of the reactant and ( n ) is the reaction order.
What information does the rate constant give from the rate law?
It tells how much the reaction rate is affected by concentrations.
What information doe the rate constant give from the rate law?
It tells how much the reaction rate is affected by concentrations.
What must be known for the rate constant to be calculated from the rate law?
The reaction rate at known reactant concentrations.
How can the rate constant be determined from the rate law?
The rate constant is the reaction rate divided by the concentration terms.
What information does the rate constant give the rate law?
It tells how much the reaction rate is affected by 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 the rate constant be determine from the rate law?
The rate constant is the reaction rate divided by the concentration terms.
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
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 can one determine the rate law from a given mechanism?
To determine the rate law from a given mechanism, you can use the slowest step in the reaction 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. This information can then be used to write the overall rate law for the reaction.
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.
