A mixture of 
and 
in the molar ratio 16:1 is diffused through a pin hole for successive effusions three times to give a molar ratio 1:1 of diffused mixture. Which one are not correct if diffusion is made at same 
and 
in each operation?
- Eight operation are needed to get 1:1 molar ratio
- Rate of diffusion for
after eight operations in 0.707
- Six operations are needed to get 2:1 molar ratio for
and 
in diffusion mixture
- Rate of diffusion for
and 
after six operations is 2.41
