H₂ (g) + I₂ (g) ⇌ 2 HI (g)
Here's what the equation represents:
* H₂ (g): Hydrogen gas, in its diatomic form.
* I₂ (g): Iodine gas, also in its diatomic form.
* HI (g): Hydrogen iodide gas, the product of the reaction.
* ⇌: This symbol indicates that the reaction is reversible. This means that hydrogen iodide can decompose back into hydrogen and iodine under certain conditions.
Important Note: This reaction is an example of a reversible reaction. It reaches equilibrium, where the forward and reverse reactions occur at equal rates.
