1
New cards

What are the factors that affect reaction rates

Concentration

Temperature

Catalysis

Surface Area

2
New cards

What makes a collision an “effective collision”?

Molecular Orientation

Energy of Collisions

Frequency of Collisions

3
New cards

What is Rate Law

Rate Law defines the dependency of rate on concentration

4
New cards

Name and explain two rate laws

Differential Rate Law describes the relationship between reaction rate and reactants concentration

Integrated Rate Law describes the relationship between reactants concentration and time

5
New cards

How can rate be described in an equation

example Rate = k [cyclopropane]1

6
New cards

What is the order of reaction?

Order of reaction describes the relationship between concentration of reactants and reaction rate- determined by experiment

7
New cards

What is the overall reaction order?

Is the sum of the powers to which all reactant concentrations are raised in the rate law

8
New cards

What is the Pseudo-First Order Reaction?

A reaction that is not first order naturally but is made first order by increasing or decreasing the concentration of one or the other reactants
