The model contains two varying parameters called k1 and k2 and one constant parameter called k3.

The model contains two rules:

Type Variable Formula
Rate k1 −k1 · k3 · t
Rate k2 k1 · k3 · t

where the symbol 't' denotes the current simulation time.

The initial conditions are as follows:

Value Units
Value of parameter k1 1.5 × 10−4 any
Value of parameter k2 0 same as k1
Value of parameter k3 1 second-2
