Unit 5- Kinetics Flashcards
0 order reaction graph
Graph [A] vs. time
Concentration is doubled and the rate is quadrupled(2^2)
2nd order
What affects reaction rate
6 things
Temperature, concentration, surface area, catalyst, inhibitors, intermediates
Wha is rate
Change in concentration of over time
2nd order
Concentration is doubled and the rate is quadrupled(2^2)
In an exothermic reaction is the enthalpy of the reaction negative or positive
The enthalpy is negative in an exothermic reaction
Change in H = -
What is the transition state
The peak or top of the potential energy graph also known as the activated complex
1st order reaction graph
Graph ln[A] vs. time
What do catalysts do to the reaction
Catalysts speed up reactions
Concentration is doubled and the rate doubles
1st order
Activation energy for reverse reaction
The difference between activated complex and the products
The opposite of the activation energy for the forward reaction
When identifying intermediates in the mechanism reaction look for what?
Cancels out
First gets formed as a product then acts as a reactant( opposite of catalyst)
2nd order rxn graph
1/A vs. time
Graph ln[A] vs. time
1st order rxn
Rates determines what
RDS
rate determines steps
