For the reaction CaCO₃(s)→ CaO(s)+ O₂(g)at 1 atm pressure,the values of ΔH and ΔS are both positive,and the process is spontaneous at high temperatures.Which of the following statements about this reaction is true? A)The change in entropy is the driving force for the reaction. B)The process is exothermic at high temperatures and endothermic at room temperature. C)The reverse reaction is endothermic. D)The reverse reaction is nonspontaneous at room temperature. E)ΔG at room temperature is negative.

Question

Quizplus · Accepted Answer

The reaction is spontaneous at high temperatures due to the positive change in entropy (ΔS), which becomes the driving force as temperature increases, making ΔG negative.
