The model contains one compartment called "compartment". There are two species called S1 and S2 and one parameter called k1. The model contains one reaction:
| Reaction | Rate |
| S1 → S2 | k1 · S1 · compartment |
The model does not contain any rules.
The initial conditions are as follows:
| Value | Units | |
| Initial amount of S1 | 1.5 × 10−4 | mole |
| Initial amount of S2 | 0 | mole |
| Value of parameter k1 | 1 | second-1 |
| Volume of compartment "compartment" | 1 | litre |
The species' initial quantities are given in terms of substance units 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.
