The reactions which are catalysed by one of the product formed, are called autocatalysis reactions and the process is called autocatalysis eg, 2AsH3(g) xrightarrow2As(g)+3H2(g)

Q. Which one of the following reactions is an example of auto-catalysis?

$2 A s H_{3} (s) 2 A s (s) + 3 H_{2} (g)$

$N_{2} (g) + 3 H_{2} (g) F e (s) 2 N H_{3} (g)$

$2 S O_{2} (g) O_{2} (g) NO (g) 2 S O_{3} (g)$

$C_{12} H_{22} O_{11} (l) + H_{2} O (l) H^{+} (l)$ $C_{6} H_{12} O_{6} (l) + C_{6} H_{12} O_{6} (l)$
