Reaction Rate
The change in concentration of a reactant or product per unit of time
Chemical Kinetics
The area of chemistry that concerns reaction rates
Instantaneous Rate
The value of the rate at a particular time can be obtained by computing the slope of a line tangent to the curve of the point
Rate Law
(Differential Rate Law) An expression the shows how the rate of reaction depends on the concentration of reactants
Rate Constant
The proportionally constant in the relationship between reaction rate and reactant concentrations
Order (of Reactant)
The positive or negative exponent, determined by experiment, of the reactant concentration in a rate law
