The model contains one compartment called C. There are two species called S1 and S2 and three parameters called k1, p1 and p2. 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 multiply(p1, p2)

The assignmentRule applies the functionDefinition defined as:

Id Arguments Formula
multiply x, y x · y

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 consisent with the value declared by the model definition.

The initial conditions are as follows:

Value Units
Initial amount of S1 0.1 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.
