|
Intermediate in a reaction |
substance that is produced in one step and consumed in the next step of the reaction |
|
|
Rate determining step |
the slowest step in a reaction is the rate determining step and determines the overall reaction rate |
|
|
activation energy |
minimum energy required of reactant molecules in order for the reaction to form products |
|
|
Ways to increase reaction rate |
1.) lower activation energy 2.) increase concentration of reactants 3.) increase temperature |
|
|
How does a catalyst affect reaction rate? |
It increases reaction rate by lowering the activation energy of the rate determining step (the step that has the highest transition state) a CATALYST WILL ALWAYS BE REFORMED AT THE END OF THE REACTION AND IS NOT USED BY THE REACTION |
|
|
Does a catalyst affect the thermodynamics of a reaction? |
NOOOOO |
|
|
What reactants are the ones that are part of the rate law expression? |
the reactants that are part of the rate determining step |
|
|
Arrhenius Equation |
k= Ae^(Ea/ RT) or k= lnA - (Ea/ RT) |
|
|
By how much will rate increase for every 10 degree Celsius increase in temperature |
by a factor of about 2 to 4 |
