Q. Which of the following statements regarding the reaction 2PbO(s) + C(s) → 2Pb(s) + CO₂(g) are incorrect?

1. Lead is getting reduced.
2. Carbon dioxide is getting oxidised.
3. Carbon is getting oxidised.
4. Lead oxide is getting reduced.

Select the correct answer from the codes given below:
Answer: Only 1 and 3
Notes: Lead oxide (PbO) is reduced to lead (Pb), and carbon is oxidised to carbon dioxide (CO₂). Therefore, statements 1 and 3 are incorrect: lead is actually getting reduced (not incorrect), carbon dioxide is not getting oxidised. Carbon is getting oxidised, and lead oxide is reduced. Thus, only statements 1 and 3 are incorrect.
