sci.equilibrium-constant-Kp-Kc Calculator
Converts between Kp (pressure-based) and Kc (concentration-based) equilibrium constants: Kp = Kc × (RT)^Δn, where Δn is the change in moles of gas. For N₂O₄ ⇌ 2NO₂ (Δn = +1) at 25 °C: Kp = Kc × RT = Kc × 24.5 L·atm/mol.
Inputs
Kc
Reference formula or conversion factor shown for context.
T K
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Delta N
Reference formula or conversion factor shown for context.
Results
Kp (pressure basis)
Reference formula or conversion factor shown for context.
ln(Kp)
Sample size or count used in the calculation.
ΔG° (J/mol)
Reference formula or conversion factor shown for context.
