MCQs of Chapter 11 Chemistry Class 11

Al-Huda Science Academy is focusing not only on short questions and long questions but also on MCQs of Chapter 11 Chemistry Class 11. Entry Tests required a lot of effort on Multiple Choice Questions that should be of conceptual in nature. The users can participate without login to MCQs test. All MCQs are taken from the past papers of Punjab Boards including Bahawalpur Board, DG Khan Board, Faisalabad Board, Gujranwala Board, Lahore Board, Multan Board, Rawalpindi Board, Sahiwal Board and Sargodha Board. Chapter 11 of F.Sc Part 1 Chemistry is based on Reaction Kinetics. In this chapter, students will learn about concepts of:

Concepts of Reactions ,measurements and their rates.

#1. Hydrolysis of tertiary butyl bromide is :

First order reaction

Pseudo first order reaction

Second order reaction

Zero order reaction

#2. Half life of a second order reaction is inversely propotional to:

Final concentration of products

Initial concentration of products

Final concentration of reactants

Initial concentration of reactants

#3. The order of decomposition of Nitrogen pentaoxide 2N2O5→2N2O4 +O2 is:

Third order

Second order

First order

Zero order

#4. The order of reaction for the reaction NO + O3→NO2 + O2 is:

Zero

One

Three

Two

#5. The unit of rate constant is the same as that rate of the reaction is:

Zero order

First order

Second order

Third order

#6. With increase in 10 C temperature, the rate of reaction doubles. This increase in rate of reaction is due to:

Increase in the number of effective collisions

Decrease in activation energy of reaction

Increase in activation energy of reactants

Decrease in the number of collisions between reactant molecules

810 million years

710 million years

720 million years

820 million years

#8. The rate equation of a reaction 2A + B→ products is, rate =K[A]2[B], and A is present in large access, then order of reaction is:

3

2

1

None of these

#9. In Zero order reaction rate is independent of:

Concentration of reactants

Temperature of reaction

None of these

Concentration of products

#10. The rate of reaction:

May decrease and increase as the reaction proceeds

Remains the same as the reaction proceeds

Increases as the reaction proceeds

Decrease as the reaction proceeds
