Instantaneous Rate : What It Is, How to Calculate It, and Real-World Uses

The video tutorial explains the concept of reaction rate, focusing on calculating the instantaneous rate at a specific time. It demonstrates how to draw a tangent to a curve on a graph to find the rate at 30 seconds. The example provided involves calculating the change in concentration of a substance over time, resulting in an instantaneous rate of -0.01 mole per second.

What does the change in concentration of A represent in the calculation of the instantaneous rate?

What is the value of the instantaneous rate after 30 seconds?
