Question

Write the equation for the action of heat on potassium nitrate.

Answer 1

Step 1: When potassium nitrate is heated it undergoes decomposition reaction and it decomposes into potassium nitrite$\left({\mathrm{KNO}}_2\right)$ and oxygen.
Step 2: The Chemical reaction is as follows:
$2{\mathrm{KNO}}_{3_{\left(\mathrm{S}\right)}}\stackrel{∆}{\to }2{\mathrm{KNO}}_{2_{\left(\mathrm{S}\right)}}+{\mathrm{O}}_{2_{\left(\mathrm{g}\right)}}$
