    Why initial rates were used question
    The temperature would change would affect the rate so the rate will change so initials are used
    Then for the graph initial question draw a tangent to line or curve with passing through point at 0 seconds and calcuate gradient
    2 or 3 marks for this 2 questions
    I put exactly the same for second question.

    It was 2 marks.

    Yes I got exactly that, and using the hnmr data deduced that it could only be that...then spent all my spare time trying to figure out alternate structures that didn't involve a tertiary alcohol...of which there were none.
    Omg I literally spent half an hour on that question- the whole paper was an utter joke and embarrassment.

    But yeah either wayif it's wrong we will prob get a mark for identifying the -o- and the -oh ?

    I got (CH3)2CH-CH2-O-CH(CH3)-CHOH for the last structure. The middle may be the wrong way around, as I can't remember, but I put the primary alcohol on the end and a di-methyl group on the other. Did anyone get the same?

    Im guessing that lidocaine is more soluble compared to the salt which is actually can be injected or used like a cream as it is less soluble

    The propanoic acid accepts a H+ and the nitric acid becomes NO3-

    I had HNO3 + ethanoic acid -> NO3- + H2O + CH3C+O

    (Pretty sure it was ethanoic)
