Reset the simulation again. Set the ruler at 50 and the left platform at 20. Don't add any molecules yet. Predict what will happen when you add 30 molecules of substance A. Why do you think this will happen?​

The conversion of substance A to substance B will happen extremely slowly because of the very high activation energy that each molecule must obtain to convert.

Plato answer

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
