Reaction eated/kinetics

Question 1

What does the rate of a chemical reaction normally depend on?

Answer 1

The concentrations of the reactants

Question 2

Why are orders of reaction used to do?

Answer 2

To relate the rate of a reaction to the reacting species

Question 3

rate equation

Answer 3

rate=k[A]

to the power of the order

if doubling concentration doubles rate then it would be to the power of 1

If doubling concentration quadruples rate then it would be to the power of 2

Question 4

how do you work out the overall order of a reaction?

Answer 4

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

Question 5

What is the only way of determining the order of a reaction?

Answer 5

experimental data

Question 6

How do reactions usually occur?

Answer 6

by a series of steps called a reaction mechanism

Question 7

What is the rate of reaction dependent on?

Answer 7

the slowest step->rate determining step

Question 8

overall reaction order and unit of k

Answer 8

1st: s-1
2nd: l mol-1 s-1
3rd: l2 mol-1 s-1
4th- l3 mol-3 s-1
