The model contains one compartment called C. There are two species called S1 and S2 and two parameters called k1 and k2. The model contains one reaction defined as:

Reaction Rate
S1 → S2 C · k1 · S1

The model contains one initialAssignment:

Variable Formula
k1 division(k2, 100)

The initialAssignment uses a functionDefinition defined as:

Id Arguments Formula
division x, y xy

Note: SBML's InitialAssignment construct override any declared initial values. In this model, the initial value for the parameter k1 has not been explicitly declared and must be calculated using the InitialAssignment.

The initial conditions are as follows:

Value Units
Initial amount of S1 1 mole
Initial amount of S2 1.5 mole
Value of parameter k1 undeclared second-1
Value of parameter k2 50 second-1
Volume of compartment C 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) they must be treated as concentrations where they appear in expressions.
