Part A Estimate the rate of molecular collisions (collisions/s) on this wall. Express your answer to two significant figures and include the appropriate units. Value Units the rate of collisions = Submit Give Up Continue>

Solution

Z = (pi)*d^2*v*(2)^.5

Z is the collision per unit volume per second
Z = 64*576*2^.5

Z = 52133.568 collision/m³s
