What must be known for the rate constant to be calculated from the rate law?
The reaction rate at known 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.
What is relative rate constant?
A relative rate constant the rate at which a reaction will take place. Ex. V = k [A][B] the constant ,k, is a constant value for the rate of the reaction in said equation.
How can the rate law for a a chemical reaction be used to determine an instantaneous reaction rate?
The Instantaneous rate, or the rate of decomposition at a specific time, can be determined by finding the slope of a straight line tangent to the curver at that instant.
What is the law relating pressure and volume in a gas?
This is the law of Boyle and Mariotte: pV=k. k is a constant. The temperature is supposed to remain constant.
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 is the k in the rate law equation?
A rate constant
What has the largest value of the rate constant?
how does the rate law show how concentration changes after the rate of reaction
What has the largest values of the rate constant?
how does the rate law show how concentration changes after the rate of reaction
What are m and n in the rate law equation rate kAmBn?
They are experimentally determined exponents.
What does the rate law use to determined the rate of a reaction?
The rate of a reaction is calculated using the concentrations of reactants.
What information does the rate constant give from the rate law?
It tells how much the reaction rate is affected by concentrations.
What has the largest values of the rate constant k?
how does the rate law show how concentration changes after the rate of reaction
