The model contains one compartment called "compartment". There are three species named S1, S2 and S3 and one parameter named k1. Species S3 is labeled as constant and therefore cannot be changed by rules or reactions. The model contains one reaction defined as:

Reaction Rate
S1 → S2 k1 · S1 · S3 · compartment

The initial conditions are as follows:

Value Units
Initial amount of S1 1.5 mole
Initial amount of S2 0 mole
Initial amount of S3 2 mole
Value of parameter k1 1.5 litre mole-1 second-1
Volume of compartment "compartment" 1 litre

The species values are given as amounts of substance to make it easier to use the model in a discrete stochastic simulator, but (as per usual SBML principles) their symbols represent their values in concentration units where they appear in expressions.

Note: The test data for this model was generated from an analytical solution of the system of equations.
