The model contains one compartment called C. There are three species called S1, S2 and S3 and two parameters called k1 and k2. Species S1 and S2 are labeled as SBML boundary species. The model contains two reactions defined as:

Reaction Rate
S1 + S2 → S3 k1 · S1 · S2 · C
S3 → S1 + S2 k2 · S3 · C

The initial conditions are as follows:

Value Units
Initial concentration of S1 1.0 × 10−2 mole litre-1
Initial concentration of S2 2.0 × 10−2 mole litre-1
Initial concentration of S3 1.0 × 10−2 mole litre-1
Value of parameter k1 0.75 litre mole-1 second-1
Value of parameter k2 0.25 second-1
Volume of compartment C 1 litre

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