Hello, I’m confused on number 5 part b and c. I know how to make the graph on part b but am having trouble figuring out how to estimate the instaneous rate of dissaperence of A at 15.0 s. also then on part c using all the answers together. The first pic is the textbook question. The second pic is what I have so far. the third pic is the answers in the back of the book. this is my second time posting this question… Thank you!

Chapter 12| Kinetics 702 5. A study of the rate of the reaction represented as 2A → B gave the following data: 0.0 5.0 10.0 15.0 20.0 25.0 35.0 1.00 0.952 0.625 o.465 0.370 0.308 0.230 Time (s) A] (M) (a) Determine the average rate of disappearance of A between 0.0 s and 10.0 s, and between 10.0 s and 20.0 s. (b) Estimate the instantaneous rate of disappearance of A at 15.0 s from a graph of time versus IAl. What are the units of this rate? (c) Use the rates found in parts (a) and (b) to deternine the average rate of formation of B between 0.00 s and 10.0s and the instantaneous rate of formation of B at 15.0 s
