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.
