Question

A spherical vessel of radius r = 5 cm contains hydrogen ( H 2 ​ ) at a temperature T = 300 K and pressure p = 1 0 5 Pa. How many molecules collide on the vessel in 1 s (in units of 1 0 26 , to two decimals)?

TestHub · Accepted Answer

Collisions per second = 4 1 ​ n v ˉ ⋅ 4 π r 2 with n = k T p ​ and v ˉ = πm 8 k T ​ ​ . This gives 3.38 × 1 0 26 .
