(a) Diffusion of A through non-diffing (b)Equimolar Counter diffusion

(c) Multicomponent non-equimolar counter diffusion         (d) Not related to diffusion phenomenon.

Answer 1

The breathing process within the lungs involves diffusion of A through non-diffing.

When you inhale (breathe in), air enters your lungs and oxygen from the air travels to your blood. Simultaneously, carbon dioxide, a waste gas, travels from your blood to your lungs and is expelled (breathe out). This process is known as gas exchange, and it is necessary for life to exist.
