Question
The redox reaction among the following is: 2 4 2 6 3 3 2 2 2 3 2 4 2 4 2 3 2 6 3 2 6 3 3 (A) formation of ozone from atmospheric oxygen in the presence of sunlight (B) reaction of H SO with NaOH (C) combination of dinitrogen with dioxygen at 2000 K (D) Reaction of [Co(H O) ]Cl with AgNO
Answer: C) COMBINATION OF DINITROGEN WITH DIOXYGEN AT 2000 K
💡 Solution & Explanation
N + O 2NO : The oxidation state of N changes from 0 to +2, and the oxidation state of O changes from 0 to -2 In all the remaining reactions, there is no change in oxidation states of the elements participating in the reaction. 3O → 2O 2NaOH + H SO → Na SO + 2H O (Neutralisation reaction) 3 AgNO + [Co(H O) ]Cl → [Co(H O) ](NO ) + 3 AgCl (Double displacement)
