The model contains one compartment called "compartment". There are four species named S1, S2, S3 and S4 and two parameters named k1 and k2. The model contains one reaction defined as:

Reaction Rate
S1 → S2 k1 · S1

The model contains two rules:

Type Variable Formula
Rate S3 k1 · 0.5 10−3
Rate S4 −k2 · 0.5 10−3

The initial conditions are as follows:

Value Units
Initial amount of S1 1.5 × 10−3 mole
Initial amount of S2 2.0 × 10−3 mole
Initial amount of S3 1.5 × 10−3 mole
Initial amount of S4 4 × 10−3 mole
Value of parameter k1 0.693 second-1
Value of parameter k2 0.25 second-1
Volume of compartment "compartment" 1 litre

The species have been declared as having substance units only (meaning that the attribute hasOnlySubstanceUnits is set to true). Thus, they must be treated as amounts where they appear in expressions.

Note: The test data for this model was generated from an analytical solution of the system of equations.
