Question

Complete and balance the given equation :

${\mathrm{O}}_2\stackrel{\mathrm{Photochemical}\mathrm{reaction}}{\to }$

Answer 1

• When the oxygen molecule reacts with the UV rays of the sun, an ozone molecule is formed.
• This reaction has proceeded due to the presence of light.
• To balance the equation we multiply reactant by 3 and product by 2.

Hence, the complete balanced equation is-

$\underset{\mathrm{Oxygen}}{3{\mathrm{O}}_2\left(\mathrm{g}\right)}\stackrel{\mathrm{Photochemical}\mathrm{reaction}}{\to }\underset{\mathrm{Ozone}}{2{\mathrm{O}}_3\left(\mathrm{g}\right)}$
