Use the to simulate a system. On the “Single collision” tab of the simulation applet, enable the “Energy view” by clicking the “+” icon. Select the first A + BC ⟶ AB + C reaction (A is yellow, B is purple, and C is navy blue). Using the “straight shot” default option, try launching the A atom with varying amounts of energy. What changes when the Total Energy line at launch is below the transition state of the Potential Energy line? Why? What happens when it is above the transition state? Why?

One aspect of the collision theory and transition state theory is the role of the nature of the reactants. Using the information below, which of the following metals has the appropriate nature for this reaction to take place if B is aluminum?

The following graph shows the changes in energy that occur as the two reactions take place. Y Reaction 1 Reaction 2 Reaction Coordinate In an experiment done at a low temperature, one hour after the reaction started, Y was produced but almost no Z was produced. At a much higher temperature, one hour after the reaction started, both Y and Z had been produced. Which of the following best explains why very little Z was produced at the lower temperature? O Search or enter website name Energy
