SubstanceReactions

A substance's reactions, localised and packed.

Explained in Chemistry.

In depth

Species are local indices into the substance's own set, so a shell's composition is a dense run of the few species it can actually hold rather than a row over all sixty-eight. Reactants and products are CSR, the layout physics/faces.ts uses and for the same reason: traversal allocates nothing.

Properties

Name	Type	Description
`count`readonly	`number`
`speciesCount`readonly	`number`
`molarMass`readonly	`Float64Array`	kg/mol for each local species.
`cpA`readonly	`Float64Array`	J/(kg·K) at the standard state, and its rise per kelvin, for each local species.
`cpB`readonly	`Float64Array`
`minTemperature`readonly	`Float64Array`	K below and above which each reaction does not run, and the band the lower gate opens over.
`maxTemperature`readonly	`Float64Array`
`gateWidth`readonly	`Float64Array`
`transportLimit`readonly	`Float64Array`	The ceiling transport puts on each reaction in still air, per second. Zero means none.
`reactantStart`readonly	`Int32Array`
`reactantLocal`readonly	`Int32Array`
`reactantMoles`readonly	`Float64Array`
`productStart`readonly	`Int32Array`
`productLocal`readonly	`Int32Array`
`productMoles`readonly	`Float64Array`
`enthalpy`readonly	`Float64Array`	J per unit extent, derived by Hess's law at registration.
`table`readonly	`readonly (RateTable \| null)[]`	`null` for an instant reaction: the clamp is its only limit.
