The potential energy of a helium dimer, (he2) is given by v=(b/r^13) - (c/r^6).where b= 9.29x10^4 kj angstroms^13 (mol dimer)^-1 and c= 97.7 kj angstroms^6 (mol dimer)^-1.
a)calculate the equilibrium distance between the he atoms. b)calculate the binding energy of the dimer. c)would you expect the dimer to be stable at room temperature (300k)
