Question

pressures of SO2,SO, and O, gases, at 650
Kare respectively 0.2 bar, 0.6 bar and 0.4
bar. If the moles of both the oxides of sul-
phur are so adjusted as equal, what will be
the partial pressures of O,

Answer 1

Answer:

SO  

2

​  

 Molar mass= 32+32=64g/mol

CH  

4

​  

 Molar mass= 12+4=16g/mol

H  

2

​  

 Molar mass= 2×1=2g/mol

Rate of diffusion is inversely related to molecular weight. Lighter the gas, more is the diffusion. The rate of diffusion is given by,
