Homework Help: chemistry

hello i'm doing a redox stoichiometry lab having to do with titration

so we are given these two equations:
6 H + 3H2O2 + 2MnO4 ---> 4O2 + 2Mn + 6 H2O

6H + 5H2O2 + 2MnO4 --> 5O2 + 2Mn + 8 H2O

it asks which reactant is the source of the O2 product in this titration ?

Thank you !

I don't know which equation you are using; the source of the oxygen is H2O2 in either. I don't think the first equation is valid.
