Question

Transcribed Image Text:10.3. (a) Estimate the value of P/Paat for a sphere of radius 1 nm at 300 K if the surface tension is 1.6 J/m2
and the atomic volume is 20×10-30 m3,
Answer: P/PAat =5.2×10!
() Calculate the relative change in average partial pressure at 1300 K as the average particle size
increases from 0.5 to 10 µm.
Answer: Po.5um/P,0
(c) Would your answer in part (b) have changed much if the final diameter of the particle were that of
a 10 cm3 sphere?
Answer: Po.54m/P1ocm
= 1.0068.
10µm
21.0072.
