Explanation:
a) In the mechanism for the acid catalysed esterification of propanoic acid using ethanol, we can see that the first step is the protonation of the acid followed by nucleophillic attack of the alcohol. Loss of water and consequent deprotonation regenerates the acid catalyst. We can see the fate of the 18O labelled ethanol in the mechanism shown.
b) In the second mechanism, an unnamed ester is hydrolysed using an acid catalyst. The attack of the acid and subsequent nucleophillic attack of water labelled with 18O leads to the incorporation of this 18O into the product acid as shown in the mechanism attached to this answer.
Answer:
The concentration is
Explanation:
From the question we are told that
The absorbance is
The length is
Generally absorbance is mathematically represented as
where is the molar absorptivity of FeSCN2 with a value
and is the equilibrium concentration of FeSCN2
So
substituting values
