Question: For the reaction A B at 298 K, the change in enthalpy is -7 kJ mol-1 and the change in entropy is -25

For the reaction A → B at 298 K, the change in enthalpy is -7 kJ ∙ mol-1 and the change in entropy is -25 J ∙ K-1 ∙ mol-1. Is the reaction spontaneous? If not, should the temperature be increased or decreased to make the reaction spontaneous?
