Two of O atom, two of H atom on both sides. The reduction of gaseous oxygen to aqueous hydrogen peroxide,when this reaction in acidic aqueous solution, and we need to balance H on both sides .

How to balance the equation?

O2 (g) → H2O2 (l)

O2(g) + H+(aq) → H2O2(l)

O2(g) + 2H+(aq) → H2O2(l)

now, we need to balance 2 positive charge of 2H+ so, we will put 2 e- on left side:

O2(g) + 2H+(aq) + 2 e- → H2O2(l)

this is the final balanced equation which has equal no. of atoms on both sides:

2 of Oxygen atom, 2 of Hydrogen atom on both sides.

What is first order of reaction?

A first-order reaction can be defined as, a chemical reaction in which the reaction rate is linearly dependent on the concentration of one reactant. In other words, a first-order reaction is a chemical reaction in which the rate varies on the changes in the concentration of one of the reactants.
