Question

Identify the type of reaction

$2{\mathrm{KNO}}_3\left(\mathrm{s}\right)\to 2{\mathrm{KNO}}_2\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$

Answer 1

• The given chemical equation $2{\mathrm{KNO}}_3\left(\mathrm{s}\right)\to 2{\mathrm{KNO}}_2\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$ is a type of decomposition reaction.
• In a decomposition reaction, one chemical substance is decomposed into one or more products.
• In the given reaction Potassium nitrate(${\mathrm{KNO}}_3$) is decomposed into potassium nitrite(${\mathrm{KNO}}_2$) and oxygen(${\mathrm{O}}_2$).
