    Dehydration is a process of prograde reaction so the clockwise PT path is taken so with temperature the pressure is rising so convex upward is the curve attained

    Dehydration reaction occurs during prograde metamorphism as a result of heating of the rocks. In the shown diagram, you can observe that the path of prograde metamorphism is convex upward i.e. the dehydration reaction curve is convex upward in P-T space.
