Formula
θ=KP/(1+KP); q=qmax θ.
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- Ideal single-layer adsorption on equivalent independent sites at fixed temperature.
Example Calculation
Example inputs
- Pressure: 2 bar
- Adsorption constant: 0.5 1/bar
- Maximum capacity: 10 mg/g
P=2 bar and K=0.5/bar give half coverage and q=5 mg/g for qmax=10.
Frequently asked questions
How do I use this calculator?
Enter pressure, adsorption constant, maximum capacity. The result updates automatically. Use Reset to restore the example values.
What method does it use?
θ=KP/(1+KP); q=qmax θ.. Ideal single-layer adsorption on equivalent independent sites at fixed temperature.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
