Solid molecular hydrogen for H 2 one finds from measurements on the gas that the Lenard-Jones parameters
Question:
Solid molecular hydrogen for H2 one finds from measurements on the gas that the Lenard-Jones parameters are ε = 50 x 10-16 erg and σ = 2.96 A. Find the cohesive energy in kJ per mole of H2; do the calculation for an icc structure Treat each H2 molecule as a sphere. The observed value of the cohesive energy is 0.751kJ/mol, much less than we calculated; thus, quantum corrections must be very important.
