What phase change represented by the equation I2 (s) I2 (g)
going directly from a solid to a gas is called sublimation
In this phase change, the equation I2 (s) I2 (g) is simply telling you that I2 (solid) is transforming into I2 (gas). It's like saying, "Hey, I2 (solid), it's time to go big and become I2 (gas)! Show them your gassy side!" So, in a nutshell, it's the transition from a solid to a gas state. Keep it gassy, my friend!
The phase change represented by the equation I2 (s) → I2 (g) is the process of sublimation. Sublimation is the direct transformation of a solid substance into its gaseous state without passing through the liquid phase.
The equation I2 (s) ⇌ I2 (g) represents a phase change known as sublimation. Sublimation is the process in which a solid directly converts into a gas without passing through the liquid phase.
To understand this, let's take a closer look at the chemical formula and phase symbols:
- "I2" represents molecular iodine, which consists of diatomic iodine molecules.
- The state symbols "(s)" and "(g)" represent solid and gas phases, respectively.
In this equation, I2 (s) represents solid iodine, while I2 (g) represents gaseous iodine. It shows that solid iodine is being converted into gaseous iodine vapor.
During sublimation, the molecules of solid iodine gain enough energy to break their intermolecular forces and transition directly into the gas phase. This phase change is favored at low temperatures and low pressures.
If you are looking for information about the thermodynamics or specific conditions under which iodine undergoes sublimation, you may need to consult a phase diagram or reference materials.
