Q. The stability field boundary between two minerals A and B is linear with a positive slope in P-T space. The molar entropy of A and B are 85.5 and 92.5 Joules K-1, respectively and their respective molar volumes are 35.5 and 38.2 cc. The slope of the phase boundary in P-T space is_________________bar K-1.
