Chemical Equilibrium
Chemical equilibrium and Le Chatelier's principle. Let's look at how reactions that go both ways work.
Reversible Reaction
Two molecules of reddish-brown nitrogen dioxide join to form colorless dinitrogen tetroxide. The reverse, splitting apart, also happens, so this is a reversible reaction.
Chemical Equilibrium
As time passes, the rate at which molecules join and the rate at which they split become equal, so the amounts stop changing even though both reactions keep going. This is called chemical equilibrium.
Le Chatelier's Principle
If you add nitrogen dioxide, the reaction shifts to the right to use it up. The equilibrium moves in the direction that eases the change: this is Le Chatelier's principle.
Changing Temperature
The reaction to the right gives off heat. When warmed, it shifts left, the direction that absorbs heat, and the color gets darker; when cooled, it shifts right, and the color gets lighter.
Shifting to Ease the Change
An equilibrium shifts in the direction that eases a change in conditions, then settles into a new balance.
Create 3D explainer videos like this sample from your documents and chat
Just attach product documents, drawings, or CAD data and tell the AI in chat what video you want. The AI plans the storyboard, builds the 3D scenes, and turns it into a video with narration and captions. You pay only for what you use (a rough guide is about 3,500 credits for a 1-minute video with 2 small revisions).
