Detailed Solution

Concept: Reversible reactions occur when the reactants and products combine to return the reactants to the original state. C and D may form when A and B react, or vice versa if C and D react with A and B. This is separate from thermodynamically reversible processes.
In (1), the reaction is stabilised and irreversible because a stable precipitate of AgCl forms.
The reaction in (2) does not reverse and is irreversible because H2 gas is freed, which is no longer present in the reacting system.
In (3), the process is stabilised and irreversible due to the production of stable KCl,
It is a reversible reaction in (4) because both of the products are unstable at lower pressures and react to generate the original reactants once more.
Thereby, we can now say that Question Imageis a reversible reaction.
Hence, the correct answer is option 4.
