Term
|
Definition
| A short-lived, unstable arrangement of atoms that can break apart and re-form the reactants or can form products; also sometimes referred to as the transition state. |
|
|
Term
|
Definition
| the minimum amount of energy required by reacting particles in the order to form the activated complex and lead to a reaction. |
|
|
Term
|
Definition
| states that atoms, ions, and molecules must collide with eachother to react. |
|
|
Term
|
Definition
| the change in concentration of a ractant or product per unit time, generally calculated and expressed in moles per liter per second. |
|
|
Term
|
Definition
| A substance that increases the rate of a chemical reaction by lowering the activation energies but is not concumed in the reaction. |
|
|
Term
|
Definition
| A catalyst that exists in a different physical state than the raction it catalyzes. |
|
|
Term
|
Definition
| A catalyst that exists in the same physical state as the reaction in catalyzes |
|
|
Term
|
Definition
| A substance that slows down the reaction rate of a chemical reaction or prevents a reaction from happening. |
|
|
Term
|
Definition
| Determines the reaction order by comparing the initial rates of a reaction carried out with varrying reactant concentrations. |
|
|
Term
|
Definition
| The mathematical relationship between the rate of a chemical reaction at a given temperature and the concentrations of reactants. |
|
|
Term
|
Definition
| For a reactant, describes how the rate is affected by the concentration of that reactant. |
|
|
Term
|
Definition
| A numerical value that relates the reaction rate and the concentrations of reactants at a given temperature. |
|
|
Term
|
Definition
| A chemical raction that consists of two or more elementary steps. |
|
|
Term
|
Definition
| The rate of decomposition at a specific time, calculated from the rate law, the specific rate constant, and the concentrations of all the reactants. |
|
|
Term
|
Definition
| A substance produced in one elementary step of a complex reaction and consumed in a subsequent elementary step. |
|
|
Term
|
Definition
| the slowest elementary step in a complex reaction; limits the instantaneous rate of the overall reaction. |
|
|
Term
|
Definition
| The complete sequence of elementary steps that make up a complete reaction. |
