Answer: a) Redox Reaction
Explanation:
PbO + CO → Pb + CO₂
Oxidation States of the Elements
Reactants Products
Pb +2 0
O -2, -2 -4
C +2 +4
Since the oxidation state/number of Pb decreased, it is being Reduced.
Since the oxidation state/number of C increased, it is being Oxidized.
∴ this is a Redox Reaction
