# Rate equation watch

1. In each of the following questions, use the initial rate data to find:

1) the order with respect to each reactant and the total (overall) order
2)the rate equation
3) the rate constant k (including its units) at the experiments temperature.

b) the reaction between iodine and propanone is catalysed by H+ ions

Experiment 1 = Initial [H+] in mol dm ^-3 is 0.5
initial[propanone] in mol dm^-3 is 6
initial [I2] in mol dm^-3 is 0.02
initial rate mol dm^-3 s^-1 is 9.0 * 10^-5

Experiment 2 = Initial [H+] is 0.5
Initial [Propanone] is 6
Initial I2 is 0.04
Initial Rate is 9.0 * 10^-5

Experiment 3 = Initial H+ is 1.0
Initial Propanone is 6
Initial [I2] is 0.02
Initial rate is 1.8 * 10^-4

Experiment 4= Initial [H+] is 1.0
Initial [propanone] is 8
Initial [I2] is 0.02
Initial rate is 2.4 * 10^-4

1c) D reacts with E to form various products.

Experiment 1= Initial[ D] in mol dm^-3 is 1
Initial [E] in mol dm^-3 is 1
Initial rate in mol dm^-3s^-1 is 0.20

Experiment 2= Initial [D] is 2
Initial [E] is 1
Initial rate is 0.20

Experiment 3 =Initial [D] is 4
Initial [E] is 4
Initial rate is 0.80
2. Sorry you've not had any responses about this. Are you sure you’ve posted in the right place? Posting in the specific Study Help forum should help get responses.

I'm going to quote in Tank Girl now so she can move your thread to the right place if it's needed.

3. Hi there! I've moved this t the chemistry forum now, you should get more replies here
4. How far have you got?

How far have you got?
I'm not quite sure how to do it
6. Can you post a picture of it ?
