100
Are more spontaneous reactions faster than less spontaneous reactions?

Spontaneity does not affect speed 

100

What is a substance that slows or prevents a reaction

Inhibitor 

100

What defines for a reactant how the rate is affected by the concentration of that reactant 

reaction order

100
When a collision occurs, what is released to create a product?

energy 

200

High activation energy means that few collisions have the required energy and the reaction rate is ________-

slow 

200

Name one of the ways that can affect the rate of a reaction

reactivity, concentration, temperature, surface area, and catalysts

200

What is a numerical value that relates the reaction ratio and the concentrations of reactants at a given temperature

specific rate constant 

200

what is the letter for the specific rate constant 

300

What is the key to understanding why some reactions are faster than others

collision theory 

300

When concentrations increase, more molecules are available to do what per unit volume

collide 
300

What is an experimentally determined mathematically relationship that relates the speed of a reaction to the concentrations of the reactants

reaction rate law 

300

What is a temporary, unstable arrangement of atoms in which old bonds are breaking and new bonds are forming

activated complex 

400

What is stated as the change in concentration of a reactant or product per unit time

reaction rate 

400

What exists in the same physical state as the reaction it catalyzes

homogeneous catalyst 

400

What indicates if the rate law is first order, second order, etc....

exponent to the concentration of the reactant 

400

What exists in a physical state different than that reaction it catalyzes 

heterogenous catalyst 

500
What is the average rate of reaction when at the start of the reaction containing 1.1 M of N2O5 at 55 seconds reacts to form 1.22 M at 40s?

0.008 mol/L.s

500

What is a substance that increases the rate of a chemical reaction without being consumed in the reaction

catalyst 

500

If a reactant is doubled, quadrupling the rate of reaction, the exponent of the concentration is what 

2

500

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
