what is a constant rate of change?

That means the velocity changes over time in the same manner.

4,800
+3,700
=4,500

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.

reaction: none
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.

A constant rate of change refers to a situation where the value of a variable changes at a consistent rate over a given time period. In other words, the amount by which the variable increases or decreases remains the same throughout the entire time interval.

To calculate the constant rate of change, you need two data points representing the variable at two different times. For example, let's consider the following data:

Time 1: 4,800
Time 2: 4,500

To find the constant rate of change between these two times, you subtract the initial value from the final value:

4,500 - 4,800 = -300

In this case, the variable decreases by 300 units over the given time period. Since the rate of change is constant, you can conclude that the variable decreases by 300 units every time interval.

It's important to note that in mathematical terms, the constant rate of change can be represented by a linear function or equation. The equation would have the form y = mx + b, where "m" represents the constant rate of change.

In the context of your provided data, the rate of change equation could be expressed as:

c(t) = c₀ - kt

Where:
- c(t) represents the value of the variable at time t.
- c₀ is the initial amount or concentration of the variable.
- k is the constant rate of change.
- t is the time interval.

By plugging in the values, you can determine the specific equation for your data.
