Question

?For a particular reaction, ?H° is 67.7 kJ and ?S is 126.9 J/K. Assuming these values change very little with temperature, over what temperature range is the reaction spontaneous in the forward direction?

For a particular reaction, AH is 67.7 kJ and AS is 126.9 J/K. Assuming these values change very little with temperature, over what temperature range is the reaction spontaneous in the forward direction? Number O greater than less tharn The reaction is spontaneous for temperatures ntaneous for temperatures

Explanation / Answer

G = H - TS

G = 67.7 - T*126.39 < 0

67.7*1000/126.39 < T

T >535.643642 K
