The model contains one compartment called C. There are three species called S1, S2 and S3 and three parameters called k1, k2 and p1. The model contains two reactions defined as:

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

The model contains one initialAssignment:

Variable Formula
k2 p1 · 2

Note: SBML's InitialAssignment construct override any declared initial values. In this model, the initial value for the parameter k2 has not been explicitly declared and must be calculated using the InitialAssignment.

The initial conditions are as follows:

Value Units
Initial concentration of S1 1.0 × 10−1 mole litre-1
Initial concentration of S2 2.0 × 10−1 mole litre-1
Initial concentration of S3 1.0 × 10−1 mole litre-1
Value of parameter k1 0.75 litre mole-1 second-1
Value of parameter k2 undeclared second-1
Value of parameter p1 0.125 second-1
Volume of compartment C 1 litre
