Kinectics and Rates

What is the definition of a rate?

• how fast something goes.

• change of a thing over change in time

• a unit of measurement

• a type of currency

On a graph how is the rate represented visually?  

• different points on a graph

• the y axis

• the x axis

• the slope

What is the definition of a rate law?  

 

• how the rate of a reaction depends on the concentration of reactants

• the law that defines how any rate is created in the world

• how the rate of reaction depends on time and concentration.

• how the rate is determined by steps of a reaction

How is the rate law determined?  (Select all that apply)

• Determined through experimentation

• Determined by stoichiometry

• Determined by changes in concentrations

Tags

• B is in 2nd order

• A is in 1st order

• the reaction is in 3rd order overall

• the concentration is going to be a negative number

What defines an integrated rate law?  

• How rate is dependent on concentration

• How rate is dependent on concentration in time

• How rate changes when integrated into a half life equation.

• How rate integrates into society.

What is a half life? 

• The exact half way point a reaction will live

• A famous video game

• The time required to for half of a sample to react

• the time require for half the reaction to be complete

• True

• False

A catalyst...... 

• Speeds up an reaction

• First appears on the left and then is shows up on the right again

• Is used in Catalytic Converters

• Is fully used up after being used in a reaction
