Chemical Kinetics EAMCET

I am going to appear in the Engineering, Agriculture and Medical Common Entrance Test (EAMCET) . Will you please provide Chemical Kinetics questions for practice ?

[Quick Sam]

Here I am providing list of few Chemical Kinetics questions of Engineering, Agriculture and Medical Common Entrance Test (EAMCET) which you are looking for .

The rate constant of a first order reaction is 0.0693min-1. What is the time required (in minutes) for reducing an initial concentration of 20mol lit-1 to 2.5 mole lit-1 (2009 M)
1) 40 2) 30 3) 20 4) 10
Ans : 2

For a first order reaction at 270C the ratio of time required for 75% completion to 25% completion of reaction is
(2009 E)
1)3.0 2) 2.303 3)4.8 4) 0.477

Assertion(A): A catalyst increases the rate of a reaction.
Reason (R): In presence of a catalyst, the activation energy of the reaction increases. The correct answer is:
1. Both A and R are true and R is the correct explanation of A
2. Both A and R are true and R is not the correct explanation of A
Chemical Kinetics
3. A is true but R is not true
4. A is not true but R is true
Ans : 3
