Question

3. For complete oxidation of 2 litre of NO(g) to NO.(g)
at STP, the volume of O2(g) required at STP is
(1) 0.5 L
(2) 21
(3) 1 L
(4) 1.5 L​

Answer 1

Answer:

ans is 2 L

NO (g)+O2 (g)----------> NO3 (g)

This tells that 1l of NO burns with 1l of O2

therefore 2l of NO gas will burn with 2l of O2
