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
