Lecture Twenty Two - Reaction kinetics III Flashcards
1
Q
What is the second method that can be used to determine the order of a reaction?
A
The integrated rate laws.
This method can be used when you have data about:
- The initial concentration of a reactant.
- The concentration of a reactant after some time, t.
- Several measurements of concentration have been taken at different times.
The three integrated rate laws are:

Q
What are the three integrated rate laws for zeroth, first and second order reactions?
A
3
Q
How do the graphs of each of the rate laws look?
A
4
Q
What are the components of each of the reaction orders (table form)?
A
5
Q
How can the half life be calculated for a first order reaction?
A
The half life of a substance is the time it takes for the concentrate of that substance to fall to half of its initial value.
The rate of radioactive decay is an intrinsic property f each radioactive isotope, independent of the chemical and physical form of the radioactive isotope or temperature.
