The model contains one compartment called C. There are four species called S1, S2, S3 and S4 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 rule:

Type Variable Formula
Assignment S4 multiply(p1, S2)

The model contains one FunctionDefinition defined as:

Id Arguments Formula
multiply x, y x · y

Note that in this case the initial value of the species S4 is not explicitly declared and must be calculated by the AssignmentRule.

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 1.5 × 10−2 mole litre-1
Initial concentration of S4 undeclared mole litre-1
Value of parameter k1 0.75 × 102 litre mole-1 second-1
Value of parameter k2 0.25 × 10−1 second-1
Value of parameter p1 0.75 dimensionless
Volume of compartment C 0.86 litre
