Question

Which of the following is a redox reaction? (A) Reaction of H2SO4 with NaOH (B) In atmosphere, formation of O3 from O2 by lightening (C) Formation of oxides of nitrogen from nitrogen and oxygen by lightening (D) Evaporation of H2O

Tardigrade Admin · Accepted Answer

(a) Neutralisation reaction (b) 3O2 → 2O3, allotropic formation (c) N2 + O2 → 2NO N2 is reduced and O2 is oxidised. (d) In evaporation of H2O, state changes only.

Q. Which of the following is a redox reaction?

Reaction of $H_{2} S O_{4}$ with $N a O H$

In atmosphere, formation of $O_{3}$ from $O_{2}$ by lightening

Formation of oxides of nitrogen from nitrogen and oxygen by lightening

Evaporation of $H_{2} O$

(a) Neutralisation reaction
(b) $3 O_{2} \to 2 O_{3}$ , allotropic formation
(c) $N_{2} + O_{2} \to 2 NO$
$N_{2}$ is reduced and $O_{2}$ is oxidised.
(d) In evaporation of $H_{2} O$ , state changes only.
