What type of weathering involves pollutants reacting with water vapor?

Chemical weathering

Explanation:

This weathering usually causes called Acid rains where the pollutants react with water vapor and produce toxins and such which weather away different stuff.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
