The effusion rate is 1.125 cm/sec for ammonia.

How to find effusion rate ?

Effusion rate (r1) HCl = 43.2 cm/min

Molar mass (m2) NH3 =17.04g/mole

Molar mass (m1) HCl =36.46g/mole

Substitute the molar masses of the gases into Graham's law and solve for the ratio.

firstly convert 43.2 cm/min into cm/sec i.e., 0.72 cm/sec

Then,

0.72/r2 =√17.04/36.46

r2= 1.125 cm/sec

Hence, the rate of diffusion of ammonia is 1.125 times faster than the rate of diffusion of hydrogen chloride.
