Determine order of reaction for the reactant A and B based on this rate law:
Rate = K [A]2[B]1
[A] first order and [B] first order
[A] first order and [B] second order
[A] second order and [B] first order
[A] second order and [B] second order
What is the unit for rate constant,K if rate law:
Rate = K [A]
s-1
M s-1
M-1 s-1
M-2 s-1
Given the chemical equation, Haber Prosess
N2(g) + 3H2 (g) --> 2NH3 (g)
Based on this reaction, first order for concentration N2 and zero order for concentration H2.
Write rate law:
Rate = K [N2]1 [H2]1
Rate = K [N2]1
Rate = K [H2]0
Rate = K [N2]1 [H2]3
What happened to the rate of reaction, if concentration of reactant is 'zero order'.
rate of reaction will become double
rate of reaction will become triple
rate of reaction will become quadrapel
No affect to the rate of reaction
Given rate = k[A][B]2 for the reaction of 3A + B -> 2C
What will happen to the rate of reaction if we triple [B]?
Rate will increase.
Rate will increase at a factor of 3.
Rate will increase at a factor of 6.
Rate will increase at a factor of 9.
Determine the value of rate constant, K based on this table
Rate = K [Q]2
1.0 M-1 s-1
2.0 M-1 s-1
3.0 M-1 s-1
4.0 M-1 s-1
Which of the rate law refer to the unit of the rate constant, K is M-2s-1.
rate = K [ A ] [ B ]
rate = K [ A ] [ B ]2
rate = K [ A ]2
rate = K [ A ]2 [ B ]2

and zero order for B. Which of the statements
is TRUE?
rate law is rate = k[A[2[B]
Reaction rate will increase with increase of concentration of B.
Reaction rate does not depend on the concentrations.
Reaction rate increases with increase of concentration of A.
