- The rate equation for a certain reaction is given by
Rate = k[P].
Which one of the following is the rate determining step of the reaction?
P ---> Q + S
-The rate equation for a certain chemical reaction is given by
Rate = k[P][Q][R].
Which one of the following is the slow step of the reaction?
P + Q + R ---> X + Y
- Activation energy is the
minimum energy which the molecules of the reactants must acquire before a reaction can occur.
The__________ with respect to a given reactant is the power of the reactant's concentration in the experimentally determined rate equation.
order of a reaction
2-Bromobutane cannot be prepared by
1-butene and bromine
Which one of the following is neither a nucleophile or an electrophile?
H3O+
Chlorofluorocarbons or CFCs in the stratosphere can destroy the ozone layer that protects us from the Sun's harmful ultraviolet radiation. Which one of the following is the propagation step of this reaction?
Cl atom + O3 (ozone) -----> O2 + ClO radical
A certain reaction can be represented by the following equations:
A + B --------> C slow
C --------> D + E fast
What is the rate equation for this reaction?
Rate = k[A][B]
A nucleophile is best described as
a negative ion
Which one of the following is not a Lewis base?
Ammonia
1-Bromopropane can be prepared by reacting phosphorous tribromide with
1-Propanol
The rate of the following reaction:
P + Q -----> R + S
is zero order with respect to P. It means that
xno P molecules possess sufficient energy to react, x the rate of reaction is proportional to the concentration of Q
