3.1.9 Rate equations

Question 1

How do you calculate the gradient/rate of a graph ?

Answer 1

Change in Y / Change in X

Question 2

What is the rate equation ?

Answer 2

Rate = K[A]m[B]n

Question 3

What is K ?

Answer 3

The rate constant

Question 4

What do m and n stand for ?

Answer 4

The orders of the reaction

Question 5

If [A] changes and the rate stays the same, the order of the reaction with respects to A is ____?

Answer 5

0

Question 6

If [A] doubles and the rate doubles , the order of the reaction with respects to A is ____?

Answer 6

1

Question 7

If [A] doubles and the rate becomes 4 times faster, the order of the reaction with respects to A is ____?

Answer 7

2, as 2^2 = 4

Question 8

If the rate constant gets larger what does this mean ?

Answer 8

The reaction will be faster

Question 9

What happens to rate constant if temp increases ?

Answer 9

It also increases

Question 10

Can a rate equation be worked out from a reaction equation ?

Answer 10

No as it does not tell you anything about the orders

Question 11

What is the rate determining step ?

Answer 11

It is the slowest step in a reaction, It is the slowest because it has the highest activation energy for a successful collision
