Heterogeneous catalysis

Vedclass · Answer

(A) The correct answer is $A$. The catalytic process in which the reactants and the catalyst are in different phases is known as heterogeneous catalysis.$N_{2(g)} + 3H_{2(g)} \xrightarrow{Fe(s)} 2NH_{3(g)}$In this reaction,the reactants ($N_2$ and $H_2$) are in the gaseous state,while the catalyst $(Fe)$ is in the solid state. Since they exist in different phases,it is an example of heterogeneous catalysis.
