The question asked you to find the order with respect to H+;
The concentration of H+ (mol dm-3) and rates are;
Experiment 1- 0.005. / rate- 5.75x10^-6
Experiment 2- 0.005. / rate- 1.15x10^-5
Experiment 3- 0.010. / rate- 2.30x10^-5
I said that H+ was 2nd order because if you double the concentration from 0.005 to 0.010, the rate quadruples from 5.75x10^-6 to 2.30x10^-5?
However the mark scheme says that H+ is zero order so I'm just really confused atm.
The paper is Ocr Jan 2010/ the old spec!
Please can someone help!
