Define reaction rate. Distinguish between the initial rate,
average rate, and instantaneous rate of a chemical reaction. which
of these rates is usually fastest? The initial rate is the rate
used by convention. Give a possible explanation as to why?
(I have defined all rates. I am mainly stumped on which rate is the
fastest and why initial rate is used by convention)

b. Calculate the rate of the reaction described in part a) when
[X] = 0.25 mol/L and [Y] = 6.0 mol/L.
Can you explain the difference between the rate of a reaction, the reaction rate, and the rate law? Also is there a difference between average rate of concentration change and instantaneous rate of concentration change, and how do they relate to the rate law? Please explain!

A. If the rate law for the reaction
2A + 3B products
is first order in A and second order in B, then what is the rate
law?
B. A reaction was found to be third order in A. If the
concentration of A is increased by a factor of 3, Then how much the
reaction rate will be affected?
C. The overall order of a reaction is 2. What will be the unit
of the rate constant? Show calculation....

The rate law for the reaction between catalase and hydrogen
peroxide can be written as Rate = k [H2O2]x [catalase]y. A catalase
solution of unknown, but constant concentration is prepared. Can
the partial order with respect to the peroxide (x) be found using
this catalase solution? If so, how would you do it? Describe in
detail the steps you would take or show a calculation.
