The following reaction is exothermic. 2 N2O(g) 2 N2(g) O2(g) This means the reaction: 56) A) will be spontaneous only at low temperatures B) is not spontaneous at any temperature C) will be spontaneous only at high temperature D) will be spontaneous at all temperatures E) cannot determine without temperature

Respuesta :

For exothermic processes, spontaneity will only occur if the entropy positive with all temperature or if the entropy is negative with only low temperature.

Since the given equation decomposed from 2 moles of gas into 3 moles of gas, we know that entropy is positive. Thus the reaction will be spontaneous at all temperature.

D is the answer
