In class we said that an approximate form for the bond stretch potential is V = k. -stretch (r-r)². Derive an expression for the root mean squared (RMS) stretch deviation of the bond length from ro at temperature T. What value of Kstretch would you need at 300K for the RMS deviation to be 5% the length of a typical C-C single bond? What is the force (magnitude and direction) on one of the atoms in a C-C bond that is stretched 7% longer than ro?

In class we said that an approximate form for the bond stretch potential is
V = k.
-stretch (r-r)². Derive an expression for the root mean squared (RMS)
stretch
deviation of the bond length from ro at temperature T. What value of Kstretch would
you need at 300K for the RMS deviation to be 5% the length of a typical C-C
single bond? What is the force (magnitude and direction) on one of the atoms in a
C-C bond that is stretched 7% longer than ro?
