Answer the follow using the Energy Profile plot. More than one answer is possible for some questions.
What chemical species are present...
A. at the longest constraint distance? (Use i, ii, iv, etc. for your answer)
B. at the highest energy? (Use i, ii, iv, etc. for your answer)
C. at the shortest constraint distance? (Use i, ii, iv, etc. for your answer)
i. CV+
ii. -OH
iii. CVOH
iv. transition state
In lab manual it says
long distance = reactants (CV+ and -OH)
transition state = highest energy
lowest energy or lowest distance = products (CVOH)
page 7
Longest constraint distance: CV+ and -OH (i, ii)
Highest energy: transition state (iv)
Shortest constraint distance: CVOH (iii)
yup that's right :)
the answers above are right :)
To answer these questions using the Energy Profile plot, you need to look for specific features on the plot. Here's how you can approach each question:
A. To identify the species present at the longest constraint distance, you need to locate the point on the energy profile where the distance between the chemical species is maximized. Typically, this would be at the highest energy point before the reaction or transition state occurs. Look for a point that represents the reactants at their maximum distance from each other. Once you locate this point, you can identify the chemical species present at that distance.
B. To find the species at the highest energy point, you need to look for the peak or the highest point on the energy profile. This peak usually signifies the transition state, where the system has the highest energy during the reaction process. Identify the point where the energy is highest and determine which chemical species are present at that point.
C. To determine the species at the shortest constraint distance, you need to identify the point on the energy profile where the distance between the chemical species is minimized. This point is typically located near the end of the reaction or transition state. Once you identify the point where the distance is minimized, you can determine which species are present at that distance.
Keep in mind that without specific details about the energy profile plot or the reaction being depicted, it is difficult to provide precise answers. However, by following these general guidelines, you should be able to identify the chemical species present at the longest constraint distance, highest energy, and shortest constraint distance on the energy profile plot.
