Chapter 12: Q67 E (page 710)

Use the PhET Reactions & Rates interactive simulation (http://openstaxcollege.org/l/ 16PHETreaction) to simulate a system. On the 鈥淪ingle collision鈥� tab of the simulation applet, enable the 鈥淓nergy view鈥� by clicking the 鈥�+鈥� icon. Select the first A + BC鉄禔B + C reaction (A is yellow, B is purple, and C is navy blue). Using the 鈥渁ngled shot鈥� option, try launching the A atom with varying angles, but with more Total energy than the transition state. Whathappenswhen the A atom hitstheBC molecule from different directions? Why?

Short Answer

Expert verified

In both cases, the reaction rate depends on the orientation and energy of the reactants.

In all the cases where reactant A hits the molecule BC from different directions, the reaction rate depends on the orientation and energy of the reactants.

Step by step solution

01

A hits BC from different directions

When Reactant A hits BC from different directions, not all collisions lead to the forward reaction.

02

Explanation

Reactant A has sufficient energy to react with BC. However, proper orientation of the molecules is required to bring about the reaction. So proper orientation along with total energy will determine product formation.

In the PhET Reactions & Rates (http://openstaxcollege.org/l/16PHETreaction) interactive, on the Many Collisions tab, set up a simulation with 15 molecules of A and 10 molecules of BC. Select 鈥淪how Bonds鈥� under Options.

  1. Leave the Initial Temperature at the default setting. Observe the reaction. Is the rate of reaction fast or slow?
  2. Click 鈥淧ause鈥� and then 鈥淩eset All,鈥� and then enter 15 molecules of A and 10 molecules of BC once again. Select 鈥淪how Bonds鈥� under Options. This time, increase the initial temperature until, on the graph, the total average energy line is completely above the potential energy curve. Describe what happens to the reaction

For each of the following pairs of reaction diagrams, identify which of the pair iscatalyzed:

A study of the rate of the reaction represented as 2A鉄� B gave the following data:

  1. 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.
  2. Estimate the instantaneous rate of disappearance of A at 15.0 s from a graph of time versus (A). What are the units of this rate?
  3. Use the rates found in parts (a) and (b) to determine the average rate of formation of B between 0.00 s and 10.0 s, and the instantaneous rate of formation of B at 15.0 s.

In terms of collision theory, to which of the following is the rate of a chemical reaction proportional?

(a) the change in free energy per second

(b) the change in temperature per second

(c) the number of collisions per second

(d) the number of product molecules
