1. The problem statement, all variables and given/known data The Monovacancy formation energy of a metal is 80 kJ/mol. Hence the monovacancy concentration (CV) at 25 degrees celsius is about: A)1.3x10^-13 B)9.5x10^-15 C).9 D)5x10^15 3. The attempt at a solution I know the answer is B but I dont know how to get to that. I have no book for this course (professor told us not to worry about getting it because everything we need will either be given in lecture or found on the internet). I dont have any notes on this and google is not returning anything helpful. I was wondering if someone would be willing to walk me through how to solve this problem.
