For part c, we are calculating the certain temperature that changes the reaction from nonspontaneous to spontaneous. Therefore, we use the equation deltaG=deltaH-TdeltaS. Plugging in the values given for enthalpy and entropy we set this equation to 0>enthalpy-T*entropy and solve for T. You make the equation less than 0 because negative delta G values are spontaneous. This temperature value will show you when the reaction goes from nonspontaneous to spontaneous.
