PV = nRT
V = (RT/P)n
Under constant temperature and pressure, V = constant × n
V is directly proportional to n.
Hence, the volume ratio of gas is equal to the mole ratio under constant T and P.
====
2NO(g) + O₂(g) ⇌ 2NO₂(g)
OR: Volume ratio NO : O₂ = 2 : 1
Volume of NO(g) reacted = 50 cm³
Volume of O₂ reacted = (50 cm³) × (1/2) = 25 cm³
V = (RT/P)n
Under constant temperature and pressure, V = constant × n
V is directly proportional to n.
Hence, the volume ratio of gas is equal to the mole ratio under constant T and P.
