NEET2022ChemistryRedox ReactionsActual
Which of the following reactions is a decomposition redox reaction?
Options
- A2 ~Pb ( NO ₃ )₂( ~s ) 2 PbO ( s )+4 NO ₂( ~g )+ O ₂ (g)
- BN ₂( ~g )+ O ₂( ~g ) 2 NO ( g )
- CCl ₂( ~g )+2 OH ( aq ) ClO ⁻( aq )+ Cl ⁻( aq )+4 H ₂ O (l)
- DP ₄( ~s )+3 OH ( aq )+3 H ₂ O ( l ) PH ₃( ~g ) +3 H ₂ PO ₂⁻( aq )
Correct answer
A. 2 ~Pb ( NO ₃ )₂( ~s ) 2 PbO ( s )+4 NO ₂( ~g )+ O ₂ (g)
Step-by-step solution
Redox decomposition reaction is associated with breakdown of a large molecule into smaller molecule with change in oxidation state.
