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

Reaction Rate
S1 → S2 k1 · S1 · C

The model contains two rules:

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

The initial conditions are as follows:

Value Units
Initial concentration of S1 1.5 mole litre-1
Initial concentration of S2 2.0 mole litre-1
Initial concentration of S3 1.5 mole litre-1
Initial concentration of S4 4 mole litre-1
Value of parameter k1 0.75 second-1
Value of parameter k2 0.25 second-1
Volume of compartment C 0.5 litre

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