Use boundary

Calculation path

Convert Kc to Kp from temperature and the net change in gaseous stoichiometric coefficients. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.

Calculation path

K_p = K_c(RT)^(Delta n_gas)

What you provide

What you provide

  • Concentration equilibrium constant, using the same scenario as the other inputs
  • Absolute temperature expressed in K, using the same scenario as the other inputs
  • Gas product minus reactant coefficients, using the same scenario as the other inputs

What you receive

What you receive

  • Pressure equilibrium constant from the stated equation
  • A symbolic formula plus substituted working with your values
  • Visible assumptions, field guidance, and an authoritative learning reference

Use boundary

Choose the maximum decimal places shown. This does not increase source accuracy.

Use dimensionless standard-state constants, absolute temperature, and only gaseous species in delta n.

Use internally consistent units and retain extra precision when carrying the result into another calculation.
