In а mоlecule, yоu cаn think оf the bond connecting two аtoms as a spring. If you pull the two atoms apart, the strength of the bond is proportional to the work you need to do to pull them apart. The force is given by the equation F(x) = - k * x where k is the proportionality constant called the spring constant. Part A. Do you expect k to be bigger or smaller for a double bond as compared to a single bond? Explain your answer. Part B. Calculate the work you need to do to move an atom from the equilibrium distance between the two atoms of a carbonyl bond, C = O , to 5 Angstroms apart. The equilibrium distance between C and O is 1.229 Angstroms The spring constant k is 570 kcal/(mol*Angstroms^2) 1 Angstrom is equal to 0.1 nm Solve this problem on paper, document your approach and provide intermediate results. Report the final answers with 3 significant figures. Scan the pages(s) and upload them for grading. Answer both parts A and B. Please do not enter text in the box below.
