Question

Air is composed of about 79 mol% N2 and 21 mol% 02. What is the frequency of binary collisions of all kinds at 300 Kand 1 atm total pressure? The radius of N2 is 1.6 A and the radius of 02 is 1.5 A. Think of an approximate and simpler way to calculate the frequency of binary collisions of all kinds. How does your approximate answer compare with the one you calculated initially?

Answer 1

Frequency of binary collisions = 85.178 * 10^9 / sec

Step-by-step explanation:

Given data

composition of air ; 79 mol% of N2 and 21 mol% of O2

A) determine the frequency of binary collisions of all kinds at 300 K and 1 atm total pressure

= 85.178 * 10^9 per second

attached below is the detailed solution
