Evaluate the energy for vacancy formation

Reference no: EM13554929

The number of vacancies in some hypothetical metal increases by a factor of 6 when the temperature is increased from 1100 K to 1200 K. Calculate the energy (in J/mol) for vacancy formation assuming that the density of the metal remains the same over this temperature range.
