Question

Why it is more appropriate to write reactions $O_{3} (g) + H_{2} O_{2} (l) \to H_{2} O (l) + 2 O_{2} (g)$ as : $O_{3} (g) + H_{2} O_{2} (l) \to H_{2} O (l) + O_{2} (g) + O_{2} (g)$ ?
Also suggest a technique to investigate the path of the above redox reaction.

Solution

Oxygen is produced from ozone and hydrogen peroxide. Adding reaction (1) and (2) gives reaction as shown. Hence, it is more appropriate to write reaction as $O_{3} (g) + H_{2} O_{2} (l) \to H_{2} O (l) + O_{2} (g) + O_{2} (g)$
$O_{3} (g) \to O_{2} (g) + O (g)$ ......1
$H_{2} O_{2} (l) + O (g) \to H_{2} O (l) + O_{2} (g)$ ......2
$O_{3} (g) + H_{2} O_{2} (l) \to H_{2} O (l) + O_{2} (g) + O_{2} (g)$ .......3
The path of the reactions can be traced by using isotope $H_{2} O_{2}^{18}$ in reaction (b)

Consider the reactions:

(a) 6 CO₂(g) + 6H₂O(l) → C₆ H₁₂ O₆(aq) + 6O₂(g)

(b) O₃(g) + H₂O₂(l) → H₂O(l) + 2O₂(g)

Why it is more appropriate to write these reactions as:

(a) 6CO₂(g) + 12H₂O(l) → C₆ H₁₂ O₆(aq) + 6H₂O(l) + 6O₂(g)

(b) O₃(g) + H₂O₂ (l) → H₂O(l) + O₂(g) + O₂(g)
