Question

For the reaction A + B --> C + D, delta H (at STP)= +100kJ and delta S= -200J/K. {both enthalpy and entropy are at STP}a.)spontaneous at temperature greater than 500 K.b.)spontaneous at temperatures less than 500 K.c.)spontaneous at temperatures less tha -500 K.d.)spontaneous at all temperatures.e.) non-spontaneous at all temperatures.[please choose an answer, and give an explanation as to why this is the answer.]
