The model contains one compartment called C. There are three species called S1, S2 and S3 and one parameter called k1. Species S3 is labeled as constant and therefore cannot be changed by rules or reactions. The model contains one reaction defined as:

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

The initial conditions are as follows:

Value Units
Initial concentration of S1 1.5 mole litre-1
Initial concentration of S2 0 mole litre-1
Initial concentration of S3 2 mole litre-1
Value of parameter k1 1.5 litre mole-1 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.
