IIT JEE : Rates Of Chemical Reactions And Chemical Kinetics QUESTIONS AND ANSWERS :: part2 : 6 to 10

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

6.A catalyst is a substance shich

Increases the equilibrium concentration of the product
Changes the equilibrium constant of the reaction
Shortens the time to reach equilibrium
Supplies energy to teh reaction.

7.For a chemical reaction under a given set of experimental conditions, with increase in conc. of reactants, the rate of reaction generally

decreases
remains unaltered
increases
first decreases and then increases.

8.Rate equation is the expression that gives the relationship between the rate of reaction and

concentration of products
decrease in concentration
concentration of reactants
rate constant

9.In many cases, the reaction is a sequence of steps so the overall rate is controlled by

hydrolysis of each step
catalysts of different types
experimental conditions
slowest step

10.In which case the per cent increase in the rate will be maximum, when temperature isn increased from

270 K to 280 K
280 K to 290 K
290 K to 300 K
In all the three cases the increase will be same.
