The ratio of rates of diffusion of helium (He) to hydrogen ( H ₂ ) .
Options
- A2 : 1
- B1: 2
- C1: 4
- D1: 1.229
Correct answer
B. 1: 2
Step-by-step solution
Molecular mass of H ₂=2 Molecular mass of He =4 aligned Rate of diffusion of He Rate of diffusion of H ₂ & = Molecular mass of H ₂ Molecular mass of He & = 2 4 = 1 2 r_ He : r_ H ₂ & =1: 2 aligned
