Topic 16: Rate Equations Flashcards
Rate of reaction
The change in concentration of a substance per unit time
Rate equation definition
Expression to show the relationship between the rate of reaction and the concentration of reactions.
What is the order of a reactant
The power to which the reactant’s concentration is raised in the rate equation
Overall order
The sum of the powers of the concentration terms in the rate equation
Rate constant
The constant of proportionality in the rate equation
Activation energy
The minimum energy required for the reaction to occur
Reaction mechanism
A proposed sequence of discrete chemical reaction steps that can be deduced from the chemically observed rate equation.
Rate determining step
THe slowest step in a multi-step reaction sequence; it dictates the overall rate of the reaction.
