At 10°C below the melting point of aluminum, 0.08% of the atom sites are vacant. At 484°C only 0.01% are vacant. Given this information, determine the energy of vacancy formation (ΔHv) for aluminum. Energy of vacancy formation (in joules / vacancy):

this is not a chemical engineering problem per se. its more of thermodynamics, i suggest you consult mechanical engineers

this is not a chemical engineering problem. consult physicists

you won't understand it is a course

what course is that? i am a chemical engineer

Na una test qstn u con bring here ba??Go and read your advance corrosion engineering under bonding and solidification.

have you somewhat related the energy of vacancy to enthalpy change?

May b a Metallurgical & Materials Engineer would do justice 2 it
