Test: Chemical Kinetics - 2 - Question 6

Molecularity of a reaction

Detailed Solution for Test: Chemical Kinetics - 2 - Question 6

Molecularity is defined as the number of molecules, atoms, or radicals that must collide simultaneously in order for the reaction to take place. It is always a whole number (except zero) and cannot be negative.

Test: Chemical Kinetics - 2 - Question 7

For which of the following reaction the units of rate constant and rate of the reaction are same?

Detailed Solution for Test: Chemical Kinetics - 2 - Question 7

Test: Chemical Kinetics - 2 - Question 8

The rate of chemical reaction becomes double for every 10o rise in temperature because of

Detailed Solution for Test: Chemical Kinetics - 2 - Question 8

With increase in temperature molecular collisions increases therefore rate of reaction doubles.

Test: Chemical Kinetics - 2 - Question 9

The rate is independent of the concentration of the reactants in

Detailed Solution for Test: Chemical Kinetics - 2 - Question 9

Test: Chemical Kinetics - 2 - Question 10

A reaction whose order is different from the actual due to large excess concentration of one of the reactants is called?

Detailed Solution for Test: Chemical Kinetics - 2 - Question 10

A reaction whose order is different from the actual due to large excess concentration of one of the reactants is called pseudo 1st order reactions.

Test: Chemical Kinetics - 2 - Question 11

The role of catalyst in a chemical reaction is to change the

Detailed Solution for Test: Chemical Kinetics - 2 - Question 11

Role of catalyst is to decrease the activation energy of reaction.

Test: Chemical Kinetics - 2 - Question 12

Rate of ionic reactions are generally

Detailed Solution for Test: Chemical Kinetics - 2 - Question 12

Ionic reactions occur very fast.

Test: Chemical Kinetics - 2 - Question 13

The metabolism of hormones in human body is an example of

Detailed Solution for Test: Chemical Kinetics - 2 - Question 13

It is pseudo first order reaction.

Test: Chemical Kinetics - 2 - Question 14

If a reaction proceeds with a uniform rate throughout, the reaction is

Detailed Solution for Test: Chemical Kinetics - 2 - Question 14

Rate of reaction is independent of concentration of reactant.

Test: Chemical Kinetics - 2 - Question 15

Which among the following is an example of photochemistry used in our daily life?

Detailed Solution for Test: Chemical Kinetics - 2 - Question 15

Photography is an example of photochemistry used in our daily life.

Test: Chemical Kinetics - 2 - Question 16

The ionic reactions are generally very fast because

Detailed Solution for Test: Chemical Kinetics - 2 - Question 16

Ionic compounds in solution react faster than molecular compounds. This is because Ionic compounds break apart to form free ions. Therefore, there are no bonds to break so the reaction is fast. Covalent compounds, on the other hand, have to break bonds first as they react, so the reaction is often slower.

Test: Chemical Kinetics - 2 - Question 17

The rate constant of the reaction at temperature 200 K is 10 times less than the rate constant at 400 K. The activation energy of the reaction is  

Detailed Solution for Test: Chemical Kinetics - 2 - Question 17

Test: Chemical Kinetics - 2 - Question 18

Which among the following is an instantaneous reaction?

Detailed Solution for Test: Chemical Kinetics - 2 - Question 18

Precipitation of AgCl is an example of instantaneous reaction.

Test: Chemical Kinetics - 2 - Question 19

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

Detailed Solution for Test: Chemical Kinetics - 2 - Question 19

For second order reaction half life is inversely related to concentration of reactant.

Test: Chemical Kinetics - 2 - Question 20

If 75% of a first order reaction was completed in 32 min, then 50% of the reaction was completed in

Detailed Solution for Test: Chemical Kinetics - 2 - Question 20

75% completion means 2 half lifes so 50% completion means only one half life.

Test: Chemical Kinetics - 2 - Question 21

Milk turns sour at 40°C three times faster than it does at 0°C, this shows that activation energy of souring of milk (in cal) is

Detailed Solution for Test: Chemical Kinetics - 2 - Question 21

Test: Chemical Kinetics - 2 - Question 22

In a reaction, → Product, rate is doubled when the concentration of is doubled, and rate increases by a factor of 8 when the concentrations of both the reactants (Aand B) are doubled, rate law for the reaction can be written as 

Detailed Solution for Test: Chemical Kinetics - 2 - Question 22

The correct answer is option B
When conc. of B is doubled, the rate is doubled. 
So, Order w.r.t.  [B] is 1.
The rate increases by a factor of 8 when conc. of [A] and [B] are doubled.
So, Order w.r.t.  [A] is 2.
Overall Rate is 
Rate=k[A]2[B]

Test: Chemical Kinetics - 2 - Question 23

Thermal decomposition of a compound is of first order. If 50% of a sample of a compound is decomposed in 120 min, the time taken for 90% completion is

Detailed Solution for Test: Chemical Kinetics - 2 - Question 23

Test: Chemical Kinetics - 2 - Question 24

In the catalyzed decomposition of benzene diazonium chloride, 

Half life period is found to be independent of the initial concentration of the reactant. After 10 min, the volume of Ngas collected is 10 L and after the reaction is complete, it is 50 L. Hence, the rate constant of the reaction(in min-1) is

Detailed Solution for Test: Chemical Kinetics - 2 - Question 24

Test: Chemical Kinetics - 2 - Question 25

Decomposition of  H2Owas studied by titration against KMnOsolution. It was found that 0.4 mol of H2Owas reduced to 0.2 mol in 20 min and to 0.1 mol in 40 min and to 0.05 mol after 1 hr, the order of reaction must be

Detailed Solution for Test: Chemical Kinetics - 2 - Question 25

For 1st order reaction, 
Co  (t1/2)→Co/2  (t1/2)→Co/4  (t1/2)→…….Co/2n
Here, t1/2 = 20
So after 1st half life, concentration should be 0.4/2 = 0.2 
After 2nd half life, concentration should be 0.4/4 = 0.1
This is correct with given data. So the order is 1st order.
