what is a constant rate of change?
That means the velocity changes over time in the same manner.
Rate of Change Is Constant
You can increase or decrease the amount or concentration of a species by a constant value using a zero order rule. For example, the species c increases by a constant rate k. You could also include species and parameters that have their ConstantAmount or ConstantValue properties selected.
rate equation: none
rate rule: dc/dt = k
species: c = 0 mole
parameters: k = 1 mole/secondThe solution is , where is the initial amount or concentration of the species c.
Enter the rule described above as c = k. From the RuleType list, select rate, enter the values for c and k, and then simulate.
