I'm not sure why I am unable to attach diagrams at this moment..
Q11
Answer: C
A reaction with autocatalysts will start off relatively slow.The rate of reaction will increase due to the production of catalysts. After a peak, the rate of reaction will decrease when the concentration of reactants are used up.
Q23
Answer: A
Sulfuric acid will hydrolyse the ester bond and create a COOH group.
The C=C double bonds in the molecules will be hydrogenated.
The COOH bond will NOT be reduced to an alcohol by the hydrogen, that would actually require LiAlH4.
Q30
Answer: B
Esterification of the both OH groups with two COOH groups (1 from each molecule of ethanoic acid)
