What is required for two molecules to react once they collide?
correct orientation
adequate activation energy (speed)
What are the four factors to effect reaction rate?
concentration/pressure
temperature
surface area
catalyst
What is the standard form of a rate law?
Rate =K[A]^x[B]^y
if Z is the factor by which your concentration changes and Y is the factor by which your rate changes, what formula could be used to find the order?
Z^n=Y
If the initial concentration is doubled, what change in the initial rate would reflect zero order?
zero order = no change in rate
If the initial concentration is doubled, what change in the initial rate would reflect first order?
first order = doubled
If the initial concentration is doubled, what change in the initial rate would reflect second order?
second order = quadrupled
If the initial concentration is doubled, what change in the initial rate would reflect third order?
third order = octupled
As the concentration of products increases, the value of K does what?
Increases, [products]/[reactants]
As the concentration of reactants increases, the value of K does what?
Decreases, [products]/[reactants]
What is the integrated rate law for a zero order reaction?
[A] vs time
What is the integrated rate law for a first order reaction?
ln[A] vs time
What is the integrated rate law for a second order reaction?
1/[A] vs time
How do catalysts increase the rate of a reaction?
By providing an alternative mechanism with a lower activation energy
