If Avogadro's number were to tend to infinity, the phenomenon of Brownian motion would
Options:
Answer:
D
Solution:
Brownian motion comes from statistical fluctuations in molecular bombardment. As NA → ∞ (fixed molar mass), each molecule becomes infinitely light and the number of impacts per second tends to infinity, so the relative fluctuation in the net impulse (sim 1/√(N)) tends to zero: the impacts balance out and the motion ceases to be observable for particles of any size. Confirms Ans: (d).
