The catalyst alters the rate of a chemical reaction by,
providing an alternative pathway with a lower Ea
changing the products formed in the direction of the reaction
providing a surface on which the molecules react
increasing the frequencies of collisions between molecules
The overall order for the reaction,
2A + B → C
is one and with respect to B the order is zero. Which of the following statements is true?
The rate law of the reaction is rate =k[A]2[B]
The formation of C is double the appearance of A
The rate of reaction would increase with increasing concentration B
The half-life of the reaction is independent on the concentration of the reactants
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
How are the exponents n and m determined?
Given the following balanced equation :
2NO(g) + Cl2(g) → 2NOCl(g)
If the rate of disappearance of Cl2 is 4.84 x 10-2 Ms-1, what is the rate of disappearance of NO?
1.45 x 10-2 Ms-1
2.42 x 10-2 Ms-1
3.67 x 10-2 Ms-1
9.68 x 10-2 Ms-1
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.
