AI Generated Solution

To show that the inversion of sugar is a unimolecular reaction, we will analyze the given data and calculate the rate constant (k) for the reaction at different time intervals. A unimolecular reaction is characterized by a first-order rate law, which means the rate of reaction depends on the concentration of a single reactant. ### Step-by-Step Solution: 1. **Identify the Given Data:** - Initial rotation (R₀) = 34.50° - Final rotation (R∞) = -10.77° (at completion of the reaction) - Concentration of lactic acid = 0.5 N ...

A student performs an experiment to determine how the range of a ball depends on the velocity with which it is projected. The "range" is the distance between the points where the ball lends and from where it was projected, assuming it lands at the same height from which it was projected. It each trial, the student uses the same baseball, and launches it at the same angle. Table shows the experimental results. |{:("Trail","Launch speed" (m//s),"Range"(m)),(1,10,8),(2,20,31.8),(3,30,70.7),(4,40,122.5):}| Based on this data, the student then hypothesizes that the range, R, depends on the initial speed v_(0) according to the following equation : R=Cv_(0)^(n) , where C is a constant and n is another constant. The student performs another trial in which the ball is launched at speed 5.0 m//s . Its range is approximately:
