Which of the following is an example of heterogeneous catalysis?

A$$4NH_{3(g)}$$ + 5$$O_{2(g)}$$ $$\xrightarrow[]{Pt_{(s)}}$$
Correct Answer
B$$2SO_{2}$$ + $$O_{2}$$ $$\xrightarrow[]{NO_{(g)}}2SO_{3}$$
C$$CH_{3}COOCH_{3(l)}$$ + $$H_{2}O$$ $$\xrightarrow[]{HCl_{(aq)}}$$ $$CH_{3}COOH$$ + $$CH_{3}OH$$
D$$C_{12}H_{22}O_{11}$$ + $$H_{2}O$$ $$\xrightarrow[]{H_{2}SO_{4}}$$ $$C_{6}H_{12}O_{6}$$ +$$C_{6}H_{12}O_{6}$$

Solution

The catalytic process in which the reactants and the catalyst are in different phases is known as heterogeneous catalysis.

So here the given reaction,

In presence of $$Pt(s)$$, $$4NH_3(g)+5O_2(g)\rightarrow 4NO(g)+H_2O(g)$$

Here, $$Pt(s)$$ is in the solid-state whereas the reactants are in the gaseous state.

Hence, option $$A$$ is the correct answer.
