IIT JEE Questions And Answers :: Rates Of Chemical Reactions And Chemical Kinetics: part2



IIT JEE : Rates Of Chemical Reactions And Chemical Kinetics QUESTIONS AND ANSWERS :: part2 : 16 to 20

Following IIT JEE Entrance Multiple choice objective type questions and answers will help you in Maths, Physics and Chemistry 2024 examinations :

16.For a zero order reaction involving gaseous species, the rate of the reaction changes woth change in

concentraction
pressure
volume
temperature.

17.Rate constant is dependent on

both temperature and concentration
independent of conc. and temperature
concentration
temperature

18.The rate of reaction increases with increase in temperature. This is mainly because of

increase in collision frequency
decrease in activation energy
change in cechanism of the reaction
increase in fraction of molecules having energy equal to or greater than threshold energy.

19.For producing the effective collisions, the colliding molecules must posses

a certain minimum amount of energy
energy equal to or gerater than threshold energy
proper geometry
threshold energy and proper orientation.

20.The rate constant of which of the following reactions is independent of concentrations of the reactants?

First order reactions
Zero order reactions
Second order reactions
All of these.
