Question

What Are Thermal Decomposition Reactions? Explain With An Example.

Answer 1

Understanding the concept:

• Thermal breakdown reactions are those chemical reactions that disintegrate or decompose when heated and produce a variety of products.
• The following general formula format illustrates this:
• $\mathrm{A}\stackrel{\mathrm{Heat}}{\to }\mathrm{B}+\mathrm{C}$

Example of a thermal decomposition reaction:

• When Zinc carbonate (${\mathrm{ZnCO}}_3$) on heating decomposes to form Zinc oxide$\left(\mathrm{ZnO}\right)$ and Carbon dioxide (${\mathrm{CO}}_2$).
• Chemical equation of a given reaction;
• ${\mathrm{ZnCO}}_3\left(\mathrm{s}\right)\stackrel{\mathrm{Heat}}{\to }\mathrm{ZnO}\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)$.
