Can anyone please explain the difference between instantaneous and average rate of change?

Hey! In regards to the problem, looking at the graph, the instantaneous rate of change is the rate at a singular point, whereas the avg would be between two points on the curve (the secant line rather than a tangent)

[Melody L Lehman 2C]

Instantaneous rate of change is the rate of change of [R] or [P] at a specific time in the course of a reaction. The average rate of change is the rate of change of [R] or [P] between two designated times.

For example:
- finding the rate of change at t = 2 min would be an instantaneous rate
- finding the rate of change between t = 2 min and t = 5 min would be an average rate

Hi instantaneous rate of change is the rate of change of a single point and you would use the tangent line while avg rate of change would use two points on the curved line. To solve is problem would need to find the slope of two points on tangent line which would give you the instantaneous rate of change at t=40 s
