The motivation is to accelerate the reaction.
Why
The simplified chemical reaction is:H2 + O2 = H2O2
h2o2
There is no reaction between H2O2 and K2Cr2O7 because both are oxidants.
The reaction is:2 H2O2-----------------2 H2O + O2
Why
The reaction of NaI and H2O2 can be represented as follows:-4NaI(aq) +2H2O2(aq)---->2Na2O(s)+ 4HI(l) + O2(g)

based on the computer
The simplified chemical reaction is:H2 + O2 = H2O2
The balanced reaction for N2H4 + H2O2 --> N2 + H2O is N2H4 + 2H2O2 --> N2 + 4H2O
H2o2
The balanced equation for this decomposition reaction is 2 H2O2 -> 2 H2O + O2.
H2O2 is not a chemical reaction, it is Hydrogen Peroxide.
synthesis reaction
MnO is the catalyst in the reaction
Actually, manganese dioxide is a catalyst that speeds up the reaction but does not get consumed in the reaction and is not part of the reactants or products
