How to use the kp and kc calculator
Convert between Kp and Kc. Enter kc, δn (gas moles products − reactants), temperature in the fields above; the kp is computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- Kc — Kc
- dn — Δn (gas moles products − reactants)
- T — Temperature (K)
Worked example
With kc = 50, δn (gas moles products − reactants) = -2, temperature = 500 K, the calculator gives kp ≈ 0.02970289.
Frequently asked questions
What is the formula for the kp and kc calculation?
Kp = Kc × (0.082057 × T)^dn. Here Kc is kc, dn is δn (gas moles products − reactants), T is temperature (K).
What inputs do I need for the kp and kc converter calculator?
You need kc, δn (gas moles products − reactants), temperature in K. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
