Why is no chemical reaction necessary to extract gold?

Explanation:

Because gold is a very unreactive metal and exists as a pure substance (instead of oxides).

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.
