Answer :

The second law of thermodynamics states that the universe's entropy always rises for all spontaneous reactions (positive).

Is H favorable or unfavorable for the spontaneous process?

negative

The reaction will be spontaneous at low temperatures if -T-S is positive and -H is negative (decreasing the magnitude of the entropy term). The reaction will be spontaneous at high temperatures if H is positive and T is negative (increasing the magnitude of the entropy term).
