|
chemical kinetics
|
the study of reaction rates and reaction processes (mechanisms)
|
|
reaction rate
|
the change in concentration of reactants or products per unit time as the reaction proceeds
|
|
collision theory
|
collision between reactant molecules must be energetic enough to supply the required activation energy
|
|
collisions between reactant molecules must be ______ in a way that enables them to react with another
|
oriented
|
|
What are factors that affect reaction rates? Explain each one
|
1. nature of reactants - single bonds easier to brake than double bonds
2. surface area - more surface area will increase the reaction rate 3. temperature - higher temp, increased reaction rate 4. concentration - increasing the concentration of the reactant will increase the reaction rate 5. catalysts - addition of a catalyst will increase the reaction rate |
|
activation evergy
|
the energy required to initiate a chemical reaction
|
|
Which reactions are favored?
|
exothermic reactions are favored (decrease potential energy and increase entropy)
|
|
some reactions are _______
|
reversible - may go forward of back (increase potential energy and decrease entropy)
|
|
reactions that move forward and back at the same rate are said to be in .....
|
equilibrium
