The model contains one compartment called "compartment". There are two species called S1 and S2 and one parameter called k1, whose value is varying. The model contains one reaction defined as:

Reaction Rate
S1 → S2 k1 · S1 · compartment

The model contains one rule:

Type Variable Formula
Rate k1 0.5

The initial conditions are as follows:

Value Units
Initial amount of S1 1.5 × 10−1 mole
Initial amount of S2 0 mole
Value of parameter k1 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.
