Oes this result mean that the change in enthalpy of this, Ask an Expert

Academics

Would the change in entropy associated with the construction of an octahedral field of ligands about a metal ion be positive or negative? Briefly explain ( I think it's positive but I'm having a tough time explaining). Does this result mean that the change in enthalpy of this process must be negative in order for the process to be spontaneous under standard state conditions? How come?
