100
The formula used to calculate average reaction rate.
What is -Δ[reactant]/Δtime ?
100
Three factors that affect the reaction rate of a chemical reaction.
What are concentration, surface area, and temperature?
100
This is the formula used to calculate the rates of one-step chemical reactions.
What is rate=k[A]?
100
A reaction that consists of two or more elementary steps.
What is a complex reaction?
200
The theory that explains how chemical reactions occur in the first place.
What is collision theory?
200
It increases the kinetic energy of that substance, resulting in a greater number of collisions.
How does temperature affect reaction rate?
200
A variable that is used in the rate laws as the specific rate constant, a numerical value that relates the reaction rate and the concentrations of reactants at a given temperature.
What is k?
200
The complete sequence of elementary steps that make up a complex reaction.
What is a reaction mechanism?
300
The factor that determines whether or not a collision will result in a reaction.
What is activation energy?
300
This alters the amount of collisions taking place within a reaction, increasing reaction rate.
How does concentration affect reaction rate?
300
The general rate law.
What is rate=k[A]^m[B]^n ?
300
A substance that is produced in one elementary step of a reaction mechanism and consumed in the following elementary step.
What is an intermediate?
400
The type of reaction produced when the change in free energy (ΔG) is negative.
What is a spontaneous reaction?
400
A substance that decreases the speed of a chemical reaction.
What is an inhibitor?
400
The method of determining the value of the variables m and n in the general rate law.
What is the method of initial rates?
400
The slowest elementary step in a complex reaction.
What is the rate-determining step?
500
Supposing that there is a reaction between silver nitrate and potassium chloride, and given that there are .50 M of silver nitrate to begin and, after 10 seconds, there are .10 M of silver nitrate remaining, this is the average reaction rate of silver nitrate.
What is .04 mol/(L/s)?
500
This is a catalyst that exists in a state different from the substance it catalyzes.
What is a heterogeneous catalyst?
500
Given a table that states the initial rate of the substance is doubled when the concentration of the substance is doubled, this is the reaction order of that substance.
What is 1?
500
The factor that determines which elementary step of a complex reaction is the slowest.
What is activation energy?
