chemical kinetics

Question 1

unit of concentration

Answer 1

mol.dm-3

Question 2

rate of reaction and its unit

Answer 2

change in conc per unit time so the unit will be mol.dm-3s-1

Question 3

rate law and specific rate constant statements

Answer 3

rate law states that the rate of reaction is directly proportional to the concentration of reactant.
specific rate constant is the rate of reaction when the conc of reactant is 1 mole.

Question 4

order of a reaction

Answer 4

sum of exponents of the reactants involved in the reaction

Question 5

first order reaction and its unit

Answer 5

FIRST ORDER REACTION; when the rate of reaction is depend on power of the single reactant
UNIT: S-1

Question 6

2nd order reaction and unit

Answer 6

when the rate of reaction is depend on power of the 2 reactants
UNIT: mol-1.dm-3.s-1

Question 7

3rd order reaction and unit

Answer 7

when the rate of reaction is depend on power of the three reactant
UNIT: Mol-2.Dm6. S-1

Question 8

zero order reaction and unit

Answer 8

when the rate of reaction is not depend on conc of reactant
UNIT: Mol.Dm-3.S-1

Question 9

zero order reaction occur in? and rate increase with?

Answer 9

occur in photochemical reactions here the rate is depend on intensity of light

Question 10

substance with which bond reacts quickly

Answer 10

subs w ionic bond reacts quickly

Question 11

which properties increase rate of reaction

Answer 11

concentration of reactant, temperature and surface area.

Question 12

rate of reaction is double when?

Answer 12

temp rise by 10 C

Question 13

collision theory states

Answer 13

rate of reaction increase w increase in collision between particles

Question 15
