Kinetics




Question:
Rate law equation
Answer:
rate = k [A]^m [B]^n




Question:
Define integrated rate laws
Answer:
Relate concentrations of reactants and time

,Question:
What traits of a reaction can be determined from integrated rate law?
Answer:
-Amount of reactant or product present after a period of time
-estimated time required for a reaction to proceed to a certain extent




Question:
Define half life of reaction
Answer:
time required for half of a given amount of reactant to be consumed




Question:
Describe relationship between the half life of a first order reaction and it's rate
constant (k)
Answer:
Inverse relationship


Faster reaction (large k) = shorter half life

, Question:
Summarize the three postulates of collision theory
Answer:
-the rate of reaction is proportional to the rate of reactant collisions
-the reacting species, most collide in an orientation that allows contact
between atoms that will become bonded
-the collision must occur with adequate energy so that the electrons can
rearrange and form new bonds




Question:
How are activation energy and reaction rate connected
Answer:
- Activation energy (Ea) is the minimum energy required to form a product
during a collision of reactants
- e^-Ea/RT
- Lower Ea = faster reaction rate




Question:
Reaction mechanism
Answer:
The step-by-step process by which a reaction occurs this provides more details
on the actual events of the chemical reaction and is provided in a typical
chemical reaction
