Another functional form often utilized to represent intermoleculat forces is a Morse function, given by Vm=D[1-exp{-alpha(r-re)}]^2, where D, alpha, as well as re are constant parameters that depend upon the nature of the particles interacting.
(A) Let D=100kj mol-1, alpha=1.5A-1 (1A=10-10m) and re=2.0A. Make a careful plot of Vm versus r over the range 1.4A
(B) Illustrate that the minimum for a Morse potential occurs at r=re.
