IIT JEE : Rates Of Chemical Reactions And Chemical Kinetics QUESTIONS AND ANSWERS :: part1 : 21 to 25

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

21.In the reaction between hydrogen and nitric oxide, when the initial concentration of NO is kept constant and that of hydrogen is doubled, the reaction rate gets doubled. When the conc. of hydrogen is kept constant and that of NO is doubled, the reaction rate gets quadrupled. So order of this reaction is

22.For a first order reaction the graph will be a straight line in case the value�. are plotted.

conc. inverse Vs. time

log (conc.) Vs. time inverse

log (conc.) Vs. time

log (conc.) inverse Vs. time

23.The enzyme catalysed reaction is faster than a metal catalysed reaction because as compared to the latter, the activation energy of the former is

same

lesser

greater

none of the above

24.Half-life period of a zero order reaction is

directly proportional to cube of the conc.

directly proportional to the initial conc.

inversely proportional to the conc.

independent of the conc.

25.If half-life period is inversely proportional to the initial conc. then order of reaction is

One

Two
