This graph shows a ball rolling from A to G. The ball starts at point A and rolls to point G.

11. At what letter does the ball have the greatest kinetic energy? _
12. Which letter shows the ball when it has the maximum potential energy? _
13. Which letter shows the ball when it has the least potential energy? _
14. Why is point G slightly lower than point A? In other words, why couldn’t the ball go back to the same
height at which it started?

Six solutions are made, each with a y concentration of 1.0 μm and varying concentrations of ab as shown below. based on the concentrations, rank the solutions in decreasing order of reaction rate.
