Question
In the balanced chemical equation for the catalytic preparation of acetone by passing the vapours of a simple carboxylic acid over heated Manganese(II) oxide ($MnO$) at $300^\circ C$, what is the stoichiometric coefficient of the reactant carboxylic acid required to form exactly 1 mole of acetone?
Answer: 2
💡 Solution & Explanation
The synthesis involves the bimolecular decarboxylative condensation of acetic acid over heated MnO. The balanced equation is: $2 CH_3COOH \xrightarrow{MnO,\ 300^\circ C} CH_3COCH_3 + CO_2 + H_2O$. Therefore, 2 moles of acetic acid are required to form 1 mole of acetone.
