Ethyl 2-methylbutyrate is an ester that contributes significantly to apple's smell.
However, when heated this ester undergoes thermal decomposition into other compounds that do not smell of apple.
The rate law for the thermal decomposition of this ester was found to be:
rate = k [ester]
The rate constant k was found to be 0.025 min–1 at 95 oC.
Given that the initial concentration of this ester was 18.0 μmol dm–3 in an apple jam that was then baked at 95 oC for 15 minutes in a sealed container.
Calculate the concentration of the ester remaining at the end of the baking time. Assume there were no loss of the ester except for the decomposition concerned.
Give your answer in μmol dm–3, correct to 3 s.f. Do not type the units.
