O2 and CO2 are exchanged in the alveoli by simple diffusion. The factors that affect the diffusion are pressure gradient of the gases, solubility of the gases and the thickness of the membranes involved in diffusion.

Solution:
Reactivity of the gases
Alveolar diffusion refers to the process of gas exchange between the alveoli in the lungs and the blood in the capillaries. This exchange of gases, primarily oxygen and carbon dioxide, is crucial for maintaining proper gas concentrations in the body. Several factors influence the rate of alveolar diffusion, but the reactivity of gases is not one of them.
Factors affecting the rate of alveolar diffusion:
- Solubility of gases: The solubility of gases in the alveolar membrane affects how easily they can diffuse across it. Higher solubility allows for faster diffusion.
- Thickness of the membranes: The thinner the membrane between the alveoli and capillaries, the faster the rate of diffusion. Thicker membranes can slow down the exchange of gases.
- Pressure gradient: The difference in partial pressures of gases between the alveoli and the blood creates a pressure gradient that drives the diffusion of gases. A steeper pressure gradient leads to faster diffusion.
In contrast, the reactivity of gases, which refers to how readily they undergo chemical reactions, does not directly impact the rate of alveolar diffusion. The rate of diffusion is primarily determined by factors such as solubility, membrane thickness, and pressure gradients.
Therefore, the correct answer is option D) Reactivity of the gases.
