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

Reaction Rate
S1 → S2 C · k1 · S1

The model contains one rule which assigns value to parameter k1:

Type Variable Formula
Assignment k1 0.75

In this case there is no initial value declared for parameter k1. Thus the value must be calculated using the assignmentRule.

The model contains one initialAssignment:

Variable Formula
S1 k17.5

Note: InitialAssignments override any declared initial values. The initial value of species S1 is inconsisent with the value declared by the model definition. The value calculated by the initialAssignment should be used.

The initial conditions are as follows:

Value Units
Initial amount of S1 10 mole
Initial amount of S2 0.15 mole
Value of parameter k1 undeclared 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) their symbols represent their values in concentration units where they appear in expressions.
