Chemical Kinetics (HL)

Question 1

What is a rate equation / rate law and what is the format?

Answer 1

mathematical differential expression which expresses rate in terms of concentation, Rate = k[A]^n[B]^m

Question 2

What is the order of a reaction?

Answer 2

exponent of the concentrations of chemicals, conveys how sensitive the rate of reaction is to changes in concentrations of A and B

Question 3

What is the overall order of a reaction? How do you determine it?

Answer 3

sum of all the exponents, m+n

Question 4

What is the method of initial rates?

Answer 4

the value of the rate constant k is affected by temperature and its units are determined by the overall order of the reaction

Question 5

What is the catalyst for the contact process?

Answer 5

V2O5 / Vanadium (5) Oxide

Question 6

What is a reaction mechanism?

Answer 6

sequence of reaction steps outlining the reaction pathway from reactants to the formation of products

Question 7

What is an elementary step?

Answer 7

Individual step in the reaction mechanism
