a H2O2+O3H2O+2O2
(b) H2O2+Ag2O2Ag+H2O+O2
Role of hydrogen peroxide in the above reactions is respectively
  1. Reducing in (a) and oxidizing in (b)
  2. Oxidizing in (a) and reducing in (b)
  3. Reducing in (a) and (b)
  4. Oxidizing in (a) and (b)

Solution

In both these reactions hydrogen peroxide acts as a reducing agent, as O3 and Ag2O are reduced.
H2O2+O3H2O+2O2
H2O2+Ag2O2Ag+H2O+O2 ^
