At what temperatures is an exothermic reaction spontaneous? A. At higher temperatures when the change in entropy is negative B. At no temperatures C. At all temperatures all the time D. At all temperatures when the change in entropy is positive

You need to calculate the enthalpy change \( \left(\Delta H^{0}\right) \) of the reaction \( \mathrm{A}+\frac{1}{2} \mathrm{~B} \rightarrow \mathrm{C} \). How can the enthalpies given for the reaction steps below be combined to give the overall change in enthalpy? \[ \mathrm{A}+\mathrm{B} \rightarrow \mathrm{D} \]
