99.9%
That's about the same as a favorable reaction. At equilibrium about 99.9% has reacted.
What it means
Which way does it go?
Values are at 25 °C. Free energy scales with temperature, so the same K means a different ΔG° in a furnace.
The math
How to convert K to %
The constant and the free energy are the same statement: ΔG° = −RT ln K, which at 25 °C is ΔG° = −5.708 × log₁₀K kJ/mol.
Example: 1,000 K = 99.9001 %.
