Question

The rate of diffusion is highest for a) co2 b) N2 c) 02 d) H2

Answer 1

oxygen is more diffusable so that we can get transported it via blood vessels

Answer 2

.Diffusion is inversely proportional to molecular weight

therefore
NH3 = 14+3(1) = 17
N2 = 2(14) = 28
CO2 = 12 + 2(160 = 44
O2 = 2(16) = 32

Therefore NH3 has the highest diffusion rate .
