# General Chemistry

I have two questions about this problem, I understand how it's supposed to be done but I don't understand how my teacher came to this answer, so I was wondering if somebody could confirm or deny his answer here's the problem.

Below what temperature is: I2(g) --> I2(s)spontaneous?

When my teacher switches the equation around he ends up with this: T < -dela H/ delta S. Is that right? I would think that it would be positive

When you say "switched the equations around" are you referring to switching
I2(s) ==> I2(g)
