Question

True or False, the collision rate among methane molecules at 2000K and 1 atm does not exceed 10^9 mol/m3/sec?

Answer 1

Answer #1

The collision rate is given by the following formula:

where,

R = 8.314 J K^-1mol^-1
T = 2000 K
M = 16.04 g mol^-1

where,

R = 0.0821 X 10^-3 atm m³ K^-1mol^-1
T = 2000 K
σ= 380 pm= 380 X10^-12 m (diameter of the methane molecule)
N_A = 6.022×10²³ mol^-1
P = 1 atm

Mean Free path = 1.616 X 10^-16 m

So, the statement is false.
