In depth

Separate from the rate law because it is a different kind of statement: kinetics say how fast, a gate says whether. Ice does not melt at all below 273.15 K, and expressing that as a very small Arrhenius rate would be a lie that leaks a trickle of water into every freezer.

Properties

Name	Type	Description
`minTemperature`readonlyoptional	`number`	K. Below this, nothing.
`maxTemperature`readonlyoptional	`number`	K. Above this, nothing.
`width`readonlyoptional	`number`	K over which a gate opens rather than snapping: upward from `minTemperature`, and downward from `maxTemperature` where there is one. More Zero for a pure substance. A few kelvin for a mixture: butter softens over about three, because it is triglycerides with different melting points, and that band is what makes fat render slowly instead of switching from solid to liquid. One number for both ends, because no reaction here wants a sharp ceiling over a soft floor and a second field would be a knob nobody turns. A reaction with both gates set tapers symmetrically and is fully open only between them.
