Standard Temperature and Pressure

Ideal Gas law

The ideal gas law is a mathematical relationship between pressure, volume, temperature, and the number of moles of a gas. (Tempereature has to always be in kelvin)

 

Avargado law

At constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of gas.

Charles law

At constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

Le Châtelier’s Principle

Definition:

When a chemical system at equilibrium is disturbed, the system shifts in a direction that minimizes the disturbance.

---

What It Means:

• Equilibrium acts like a balance — when disturbed, the system "pushes back" to restore balance.

• This response helps the system re-establish equilibrium.
