The burning of coal represented by the equation;

\mathrm{C}\left( s \right) + {\mathrm{O}_2}\left( \mathrm{g} \right) \to \mathrm{C}{\mathrm{O}_2}\left( \mathrm{g} \right)\mathrm{.}

The rate of this reaction is increased by:

View answer and explanation

Correct option: B

Powdering the lumps of coal

Option B (Powdering the lumps of coal) is correct because increasing the surface area by powdering the coal increases the rate of reaction.
