Q1:

The diffusion co-efficient in m2 /s. of acetic acid in benzene (liquid in liquid) is

A 2.09 x 10-4

B 2.09 x 10-5

C 2.09 x 10-9

D 2.09 x 10-12

ANS:C - 2.09 x 10-9

The diffusion coefficient of acetic acid in benzene (liquid-liquid system) is typically in the range of 2.09×10−9 m2/s2.09×10−9m2/s. Therefore, the correct option is: 2.09×10−9 m2/s2.09×10−9m2/s.
