Question

Which statement characterizes the following table?
Temperature Dependence of Reaction Spontaneity

\begin{array} { | c | l | l | } \hline & { \Delta S < 0 } & { \Delta S > 0 } \\\hline \Delta H < 0 & \begin{array} { l } \text { Spontaneous only at a sufficiently } \\\text { low temperature. }\end{array} & \begin{array} { l } \text { Always spontaneous at any } \\\text { temperature. }\end{array} \\\hline \Delta H > 0 & \begin{array} { l } \text { Never spontaneous at any } \\\text { temperature. }\end{array} & \begin{array} { l } \text { Spontaneous only at a sufficiently } \\\text { high temperature. }\end{array} \\\hline\end{array}

Quizplus · Accepted Answer

The table correctly describes the conditions for reaction spontaneity based on the signs of enthalpy change ($\Delta H$) and entropy change ($\Delta S$).
