Section 1
Spontaneity does not affect speed
What is a substance that slows or prevents a reaction
Inhibitor
What defines for a reactant how the rate is affected by the concentration of that reactant
reaction order
energy
High activation energy means that few collisions have the required energy and the reaction rate is ________-
slow
Name one of the ways that can affect the rate of a reaction
reactivity, concentration, temperature, surface area, and catalysts
What is a numerical value that relates the reaction ratio and the concentrations of reactants at a given temperature
specific rate constant
what is the letter for the specific rate constant
k
What is the key to understanding why some reactions are faster than others
collision theory
When concentrations increase, more molecules are available to do what per unit volume
What is an experimentally determined mathematically relationship that relates the speed of a reaction to the concentrations of the reactants
reaction rate law
What is a temporary, unstable arrangement of atoms in which old bonds are breaking and new bonds are forming
activated complex
What is stated as the change in concentration of a reactant or product per unit time
reaction rate
What exists in the same physical state as the reaction it catalyzes
homogeneous catalyst
What indicates if the rate law is first order, second order, etc....
exponent to the concentration of the reactant
What exists in a physical state different than that reaction it catalyzes
heterogenous catalyst
0.008 mol/L.s
What is a substance that increases the rate of a chemical reaction without being consumed in the reaction
catalyst
If a reactant is doubled, quadrupling the rate of reaction, the exponent of the concentration is what
2
average reaction rate term is used why? (in comparison to reaction rate)
most chemical reactions slow down as reactants are consumed and fewer particles are available to collide
