Answer:
The ratio of diffusion of CO to CO2 is 5 : 4
Explanation:
Let R1 be the rate of diffusion for carbon monoxide(CO)
Let R2 be the rate of diffusion for carbon dioxide (CO2)
Let M1 be the molar mass of CO
Let M2 be the molar mass of CO2
Molar Mass of CO = 12 + 12 = 28g/mol
Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol
The rate of diffusion of a gas as explained by Graham's law of diffusion is given by
R1/R2 = √(M2/M1)
R1/R2 = √(44/28)
R1/R2 = √1.57
R1/R2 = 1.25
Converting 1.25 to fraction, we have:
1.25 = 125/100 = 5/4
Therefore R1/R2 = 5/4 i.e
R1 : R2 = 5 : 4
The ratio of diffusion of CO to CO2 is 5 : 4
