Question 1

What are orders of reactions used for?

Answer 1

Relating the rate of a reaction to a reacting species

Question 2

If changing the concentration of reactant A has no effect on the rate of reaction , what is the order of reaction in respect to A?

Answer 2

Zero order

Question 3

If doubling the concentration of a reactant A doubles the rate of the reaction, what is the order of reaction in respect to A?

Answer 3

First order

Question 4

What is the overall order of a reaction?

Answer 4

The sum of powers to which the concentrations of the reactants are raised in the rate equation

Question 5

How can the order of a reaction be determined?

Answer 5

Only from experimental data

Question 6

Reactions usually occur by a series of steps called…?

Answer 6

A reaction mechanism

Question 7

What is the rate of reaction dependent on?

Answer 7

The slowest step called the “rate determining step”

Question 8

What can be used to determine possible reaction mechanisms?

Answer 8

Experimentally determined rate equations
