JSON key: reactantsUse the array/object shape shown in the example.[{"moles":3,"coefficient":2},{"moles":2,"coefficient":1}]

Calculation method

extent = min(ni/νi); remainder = ni − extent νi

Worked examples

Worked case for limiting reactant extent calculator. Reactants only with positive balanced coefficients; zero-based indices identify limiting ties.

Limiting Reactant Extent Calculator — example with explicit inputs

Settings: No extra options

Input:

{
  "reactants": [
    {
      "moles": 3,
      "coefficient": 2
    },
    {
      "moles": 2,
      "coefficient": 1
    }
  ]
}

Expected result for the example input and options:

Output:

{
  "reaction_extent_mol": 1.5,
  "limiting_indices": [
    0
  ],
  "remaining_mol": [
    0,
    0.5
  ]
}

Limitations and common mistakes

  • Reactants only with positive balanced coefficients; zero-based indices identify limiting ties.
  • Keep JSON property names and value types consistent with the example. Network tools do not perform live scans or remote lookups.
  • Check substance identity, reaction coefficients and concentration conventions. Numerical output does not verify experimental conditions.
