First-Order Loss

First-Order Loss reactions take the form:

\[\ce{X} \rightarrow\]

where \(\ce{X}\) is the species being lost.

First-Order loss rate constants are constant over the solver time step. A conforming implementation of version 1.0 of the configuration will provide ways to set the loss rate using the name of the reaction.

Input data for first-order loss reactions have the following format:

YAML

type: FIRST_ORDER_LOSS
name: foo-loss
scaling factor: 1.2
gas phase: foo-gas
reactants:
  - species name: foo

JSON

{
    "type": "FIRST_ORDER_LOSS",
    "name": "foo-loss",
    "scaling factor": 1.2,
    "gas phase": "foo-gas",
    "reactants": [
        {
            "species name": "foo"
        }
    ]
}

The reactants key is required and must be set to a list of species being lost. The coefficient key is optional and, if not provided, is assumed to be 1.0.

The gas phase key is required and must be set to the name of the phase the reaction takes place in. Each reactant must be present in the specified phase.

The scaling factor is optional and can be used to set a constant scaling factor for the rate. When a scaling factor is not provided, it is assumed to be 1.0.

Rate constants are in \(\mathrm{s^{-1}}\).
