Hey.. I have some problems in this paper.. In q2(iii) please explain how the rate of the reaction is calculated from the graph. I get the order of reaction with respect to both reactants. have made the rate equation aswell. cant calculate the rate of the reaction and then the rate constant.
In Q3(iv) please explain to me how the PH is calculated.. If this is related to a concept that is explained somewhere on the internet.
Lastly in the q5(iv) i dont understand how the ratio of both the compounds is being calculated.
Im giving the links to the question paper and marking scheme.
Help would be really appreciated.
Thanks in advance.
