Rates of Reaction

Question 1

State what is meant by the term ‘rate of reaction’

Answer 1

The change of concentration in a given time

Question 2

Give the rate equation

Answer 2

Rate = k [A]^m x [B]^n
Where m = order for reaction for reactant A
n = order of reaction for reactant B
k = rate constant

Question 3

Describe what first order would look line on a graph

Answer 3

A straight, diagonal line going from the bottom left corner to the top right

Question 4

Describe what zero order would look line on a graph

Answer 4

A flat, straight line

Question 5

Describe what second order would look line on a graph

Answer 5

A curved line from bottom left to top right

Rate increasing at an increasing rate

Question 6

Give the Arrenhius equation

Answer 6

k=Ae ^Ea/RT
where k= rate constant
A = pre-exponential factor
R = gas constant
T = temp. in K
