Question

With the help of an appropriate example, justify that some of the chemical reactions are determined by a change in temperature.

Give a chemical equation for the reaction involved in the above case.

Give one example of a chemical reaction characterised by a change in temperature.

Answer 1

When quicklime reacts with water, slaked lime forms with the release of a large amount of heat, causing a temperature change in the reaction mixture.

\[\ce{CaO + H2O -> Ca(OH)2 + Heat}\]
