a question states that,

a) Some reactions require cooling and heating to proceed the reaction at a quicker rate, but why do we have to heat the mixture in the synthesis of aspiring?

b) When cold water was added to the reaction mixture, the aspirin produced precipitate. Yet we are able to buy it in a soluble form.
What might be the difference between aspiring and hte commercial available soluble aspirin?

c) soluble aspiring contains citric acid and sodium carbonate, what is the fizz produced when the soluble aspirin is dissolved in water

Thanks in advance, Im doing a condensed chemistry course of year 11 and 12 in a semester and i need help

sorry for the double post i couldnt see where the edit button was o.o

i solved all the answes i suppose

a) some bonds require energy to be broken, by heating it the bonds break
b) the soluble form of aspirin contains biocarbonate
c) CO2
