Go to the PhET Reactions & Rates (http://openstaxcollege.org/I/16PHETreaction) interactive. Use the Single Collision tab to represent how the collision between monatomic oxygen (O) and carbon monoxide (CO) results in the breaking of one bond and the formation of another. Pull back on the red plunger to release the atom and observe the results. Then, click on “Reload Launcher**#x201D; and change to “Angled shot” to see the difference. (a) What happens when the angle of the collision is changed? (b) Explain how this is relevant to rate of reaction .

Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.
A complete tensile test was performed on a magnesium
specimen of 12 mm diameter and 30 mm length, until breaking.
The specimen is assumed to maintain a constant volume.
Calculate the approximate value of the actual stress at breaking.
TABLE. The tensile force F and the length of the specimen are
represented for each L until breaking.
