IT IS CLEAR ENOUGH. some of the chegg experts questions are answered in this form but we make the best of it to view.. Please do the same.. The picture cant be clearer due to the paper quality.

Consider the attached phase diagram too caroon. a) Ahli for diamond (d) is 1.895 kurmole. What does this tell you whether the diamond (d graphite (g) ansition is spontaneous? by 4s so 298 K) s 0 K). For diamond as" 2,317 JAK-mole, while for graphite AS-5.740 JAK-mole. What does this tell you ahout whether the d-g transition is spontaneous? 20 woods less Aboat which state is more ordered? less). c) Determine 4Gr for diamond. Are diamonds foreven diamond is 353 d) The density of graphite is 2.25 gma em while that for gms/cm What does this tell you the of "sa-s, in the about. vicinity of the triple point? (Assume the densities are constant at all temperatures and pressures ofinterest this problem Solid (diamond) solid uraphae) 1000 2000 3000 4000 1000 Temperliure, "K

Explanation / Answer

a) Given that you are told the enthalpy of formation of diamond is positive, regardless the magnitude, it is possible to imply that energy is needed so that it is formed. This means that it takes energy to form it but it may release energy when it ceases to exist in such form. This would imply that it is not a spontaneous process when it comes to forming diamond, but it may be when it changes to another form.

Also, from the diagram shown, it is possible to observe that from diamond to graphite there is a line with a positive slope, which would tell us that the transition from diamond to graphite is, in fact, spontaneous.
