Which of the following general reaction is an example for heterogeneous catalysis?

Which of the following general reaction is an example for heterogeneous catalysis?
  1. $\mathrm{A}_2(\mathrm{~g})+\mathrm{B}_2(\mathrm{~g}) \xrightarrow{C(\mathrm{~g})} 2 \mathrm{AB}(\mathrm{g})$
  2. $\mathrm{A}(\mathrm{s})+\mathrm{B}(\mathrm{s}) \xrightarrow{C(\mathrm{~s})} \mathrm{D}(\mathrm{s})$
  3. $\mathrm{A}(\mathrm{g})+\mathrm{B}(\mathrm{g}) \xrightarrow{C(s)} \mathrm{D}(\mathrm{g})$
  4. $\mathrm{A}_2(\mathrm{~g})+\mathrm{B}_2(\mathrm{~g}) \xrightarrow{C(\mathrm{~g})} \mathrm{D}(\mathrm{s})$

Solution

In heterogeneous catalysis physical state of reactant and product is different
