Quick answer
Solve a constant-volume, one-to-one A to B equilibrium from initial concentrations and Kc. It does not solve arbitrary reaction stoichiometry or gas-phase Kp.
Formula and steps
Kc = (B0 + x)/(A0 − x); x = (Kc·A0 − B0)/(1 + Kc)
Normalize the inputs first, keep working precision through intermediate steps, and round only the displayed result. Use the Acid Base Ph when the next step requires a different chemistry model.
Assumptions and limits
Solve a constant-volume, one-to-one A to B equilibrium from initial concentrations and Kc. It does not solve arbitrary reaction stoichiometry or gas-phase Kp.
Frequently asked questions
What does this chemical equilibrium ice table assume?
The assumptions shown above are part of the result. If your system falls outside them, select a more complete method rather than forcing the number.
How should I report the answer?
Keep the units, input basis, significant figures, and model limitations with the result.
What does this calculator not do?
It does not solve arbitrary reaction stoichiometry or gas-phase Kp.
