Diffusion coefficient for ammonia in air at 25°C and 1 atm pressure can be estimated using the following formula:
D = (1.013 × 10^-7) × (T/M)^1.75
where D is the diffusion coefficient, T is the temperature in Kelvin, and M is the molecular weight ratio of ammonia to air.
Given data:
Temperature (T) = 25°C = 298 K
Pressure = 1 atm
Molecular weight of ammonia (M1) = 17 g/mol
Molecular weight of air (M2) = 29 g/mol
Calculations:
Molecular volume of ammonia (V1) = 25.81 cm^3/mol
Molecular volume of air (V2) = 24.05 cm^3/mol
Molecular weight ratio of ammonia to air (M) = M1/M2 = 17/29 = 0.586
Substituting the values in the formula:
D = (1.013 × 10^-7) × (298/0.586)^1.75
D = 0.1880 cm^2/s
Therefore, the estimated diffusion coefficient for ammonia in air at 25°C and 1 atm pressure is 0.1880 cm^2/s, which is option D.

D = 0.1880 cm^2/s
Therefore, the estimated diffusion coefficient for ammonia in air at 25°C and 1 atm pressure is 0.1880 cm^2/s, which is option D.
