Reaction Rates
This determines how quickly or slowly a reaction occur
What is kinetics
This is the rate law equation
rate = k [A]^m [B]^n
This is the processes provide an important illustration of first order kinetics.
What is radioactive decay
This is a process in a chemical reaction that occurs in a single event or step.
What is an elementary reaction
A catalyst will not appear as a reactant or product in this
What is the overall reaction
This is the change in concentration of reactant or product/change in time.
What is the rate of reaction
This letter is the rate constant
Integrated rate law for zero order reactions is this formula
[A]t - [A]o = -kt
This must be determined using experimental data.
What is the rate law
This is a substance that increases the rate of a reaction by either stabilizing the transition state or forming a new transition state.
What is a catalyst
These are the factors that increase rate of reaction
High molarity, high temperature, more surface area, and catalysts
This is the rate law for a 0 order reaction
Rate = k
Integrated rate law for second order reactions
(1/[A]t) - (1/[A]o) = kt
The process by which a reaction occurs is called this
What is the reaction mechanism
The mechanism must agree with an experimentally determined is this
What is the rate law expression
This is the unit for reaction rates
Molarity/time
This is the rate law for a 1 order reaction
Rate = k [A]
This is defined as the amount of time it takes for a radioactive sample to decay to half its original amount.
What is half life
Substances that are neither reactants or products but are formed in one elementary reaction and consumed in the next are called this
What are intermediates
Standard enthalpy of formation of the most stable form of any element is this
What is zero
According to collision theory, the rate of a reaction is influenced by anything that affects the number of or force of this
What are collisions
This is the rate law for a 2 order reaction
Rate = k [A]^2 or rate = k [A] [B]
The shorter the of this, the higher the value of k is.
What is half life
This describes the number of molecules that have to collide in an elementary step.
What is molecularity
This is a enthalpy change that accompanies the formation of a substance formation from the most stable forms of its component elements.
