Function describing exponential decline from a defined starting value, with a concentration dependent rate constant.

1 | ```
IORE.solution(t, parent.0, k__iore, N)
``` |

`t` |
Time. |

`parent.0` |
Starting value for the response variable at time zero. |

`k__iore` |
Rate constant. Note that this depends on the concentration units used. |

`N` |
Exponent describing the nonlinearity of the rate equation |

The value of the response variable at time `t`

.

The solution of the IORE kinetic model reduces to the
`SFO.solution`

if N = 1.
The parameters of the IORE model can be transformed to equivalent parameters
of the FOMC mode - see the NAFTA guidance for details.
