Identify the autocatalytic reaction from the following
1
\(1. N_2(g) + 3H_2(g) \xrightarrow[\text{Mo(s)}]{ \text{Fe(s)}} 2NH_3(g)\)
2
\(2KClO_3(s) \xrightarrow{\text{MnO}_2} 2KCl(s) + 3O_2\)
3
\(CH_3COOC_2H_5 + H_2O \longrightarrow CH_3COOH + C_2H_5OH\)
4
\(AgNO_3(aq) + KCl(aq) \longrightarrow AgCl(s) + KNO_3(aq)\)
