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
All the factors can be affected rate of reaction. EXCEPT
Concentration
Pressure
Temperature
Zuhaizi
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 3A + B -> 2C
Which statement is TRUE
Concentration A will be increase and concentration B will be decrease after reaction.
Concentration A will be increase and concentration C will be decrease after reaction.
Concentration B will be decrease and concentration C will be increase after reaction.
Concentration B will be decrease and concentration A will be increase after reaction.
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 statement will be increase the rate of reaction
Temperature must be lowered
Dilute concentration
Lower pressure
Smaller size particles
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
