Question

An example of an autocatalytic reaction is:

• A. hydrogenation of oils
• B. decomposition of nitroglycerine
• C. oxidation of $N{a}_{3}As{O}_3$ in presence of $N{a}_{2}S{O}_3$
• D. thermal decomposition of $KCl{O}_3$ in presence of $Mn{O}_2$

Answer 1

The correct option is B decomposition of nitroglycerine

Reaction mechanism for the decomposition of nitroglycerine $4C_3{H}_5{N}_3{O}_9\to 6N_2+12C{O}_2+10H_{2}0+O_2$.
This reaction is auto catalytic which is based upon internal redox chemistry.
