Solution
The correct option is D 45.24mL of SO2 Rate of diffusion=Volume of gas diffusedtime taken rO2=64t rg=Vt rO2rg=64V
Option (a) rO2rH2=√MH2MO2 64V=√232or V=256mL
Option (b) rO2rN2=√MN2MO2 64V=√2832or V=68.42mL
Option (C) rO2rCO2=√MCO2MO2 64V=√4432or V=54.58mL
Option (d) rO2rSO2=√MSO2MO2 64V=√6432or V=64√2=45.25mL
Hence, the correct answer is option (d).
