Question

In the reaction between ${SO_2}$ and ${O_3}$, the equivalent weight of ozone is

• A. the same as its molecular weight
• B. half the molecular weight
• C. one-third of the molecular weight
• D. one-fourth of the molecular weight

Answer 1

Answer: (B)

half the molecular weight

Answer 2

{3\overset{\text{ +4 }}{ { S}}$O_2 + O_3 -> 3$\overset{\text{ +6}}{ {SO}}_3} This reaction involveis two-electron change and hence, its E wt. is half its Mol. wt
