This simulation emulates the gas phase equilibria between hydrogen, bromine and hydrogen bromide molecules.
Constants:
R = 8.314
Parameters:
Hydrogen are yellow particles. (mass = 2*1.00794 u)
Bromine are red particles. (mass = 2* 79.904 u)
Hydrogen bromide are green particles. (mass = 79.904 + 1.00794 u)
N = 200 molecules
H-H bond: 436 kJ mol-1
Br-Br bond: 193 kJ mol-1
H-Br bond: 366 kJ mol-1
∆H = -103 kJ mol-1
Fixed relations
v = Math.sqrt(3*8.314/6.022*10E23*T/mass)
