1.	Suppose that a reaction has Delta H= -400kJ and Delta S = - 50J//K. A t what temperature range will it change from spontaneous to non-spontaneous?
Answer» 0.79K to 0.81 K 799 K to 801 K 801 K to 799K 0.81 K to 0.79 K Solution :Spontaneous `rArr Delta G lt 0 rArr Delta H - T Delta S lt 0` `-40 xx 1000 - T(-50) lt 0` `-40000 + 50T lt 0` `50T lt 40000` `T lt 800K` it is spontaneous
