Q. In which of the following reactions, $H_{2} O_{2}$ acts as a reducing agent

$P b O_{2} (s) + H_{2} O_{2} (a q) \to P b O (s) + H_{2} O (l) + O_{2} (g)$

$N a_{2} S O_{3} (a q) + H_{2} O_{2} (a q) \to N a_{2} S O_{4} (a q) + H_{2} O (l)$

$2 K I (a q) + H_{2} O_{2} (a q) \to 2 K O H (a q) + I_{2} (s)$

$K N O_{2} (a q) + H_{2} O_{2} (a q) \to K N O_{3} (a q) + H_{2} O (l)$

In the follow ing reaction, $H_{2} O_{2}$ acts as a reducing agent
$P b O_{2} (s) + H_{2} O_{2} (a q) \to P b O (s) + H_{2} O (l) + O_{2} (g)$
