What is the value of AG for the melting process at -10°C (263 K)? Hint: Be careful to have T and S in the same units! 4 AG=AH-TAS AG 5.26cal 1kcal mol K 1000cal AG =1.440-1.383 -0.057 0.06 kcal/mol b) Is the melting of ice spontaneous at this temperature? No quid water has AH = +1.44 kcal/mol and AS-+5.26 cal/(mol-K) 1.44 kcal mol 263 K 0°C c) If we were to recalculate with a temp 10°C would we expect the reaction to be spontaneous or non- spontaneous? Spontaneous H₂Q(s) Te melts at (d) Would the sign of AG be positive or negative? Negative Would the reaction be endogenic or exergonic?
