Chemical Kinetics Class 12 chemistry Conceptual Quiz

This quiz is specially designed to check your conceptual knowledge of chapter "Chemical kinetics Class 12" . Participate in the quiz and check yourself .

1 / 15

Half life period of any first order reaction is :

Directly proportional to the initial concentration of the reactant

Half of the rate constant

Same for all reactions

Independent of the initial concentration of the reactants

2 / 15

On increasing temperature of the reacting system by 10 degrees, the rate of reaction almost doubles. The most appropriate reason for this is :

Collision frequency increases

Activation energy decreases by increase in temperature

The fraction of molecules having energy equal to thresold energy, or more increases

The value of threshold energy decreases

3 / 15

If the rate of reaction between A and B is expressed as k[A][B]^2, The reaction is: 

First order in A

Second order in B

Overall having third order

All are correct

4 / 15

A larger increase in reaction rate with a small rise in temperature is due to: 

Increase in number of activated molecules

Increase in number of collisions

Lowering of activation energy

Shortening of mean free path

5 / 15

For the first order reaction time required for 99% completion is :

Half the time required for completion of 90% of the reaction

Thrice the time required for 90% completion of reaction

Twice the time required for 90% completion of the reaction

None of these

6 / 15

Which of the following relation is correct for zero order reaction : 

t3/4 =2 t1/2

t3/4 =1.5 t1/2

t3/4 =1/2 t1/2

t3/4 =1/3t1/2

7 / 15

For a second order reaction rate at a particular time is x. If the initial concentration is tripled, the rate will become :

3x

9x^2

9x

27x

8 / 15

A reaction is 50% complete in two hours and 75% complete in four hours. The order of reaction is :

0

1

2

3

9 / 15

Effect of temperature on reaction rate is given by: 

Claisen -Clapeyron equation

Arrhenius equation

Gibbs helmholtz equation

Kirchoff"s equation

10 / 15

The half life of a reaction is halved as the initial concentration of the reactant is doubled. The order of the reaction is :

0.5

1

2

0

11 / 15

The time taken for 90% of a first order reaction to complete is approximately :

1.1 times that of half life

2.2 times that of half life

3.3 times that of half life

4.4 times that of half life

12 / 15

According to law of mass action, the rate of a chemical reaction is proportional to

Concentration of reactants

Molar concentration of reactants

Concentration of products

Molar concentration of products

13 / 15

A reaction involving the different reactants can never be

Unimolecular reactions

First order reaction

Second order reaction

Bimolecular reaction
