Effect of temperature on spontaneity of reactions is given in the table below.
\begin{tabular}{llll}
\hline\( \Delta_{r} H^{\circ} \) & \( \Delta_{r} S^{\circ} \) & \( \Delta_{r} G^{\circ} \) & \multicolumn{1}{c}{ Description } \\
\hline\( - \) & \( + \) & \( - \) & Reaction is spontaneous at all temperature \\
\hline\( - \) & \( - \) & (II) & Reaction is spontaneous at low temperature \\
\hline\( - \) & \( - \) & \( +( \) at high \( T) \) & Reaction is non-spontaneous at high temperature \\
\hline\( + \) & \( + \) & \( +( \) at low \( T) \) & (III) \\
\hline (I) & \( + \) & \( -( \) at high \( T) \) & Reaction is spontaneous at high temperature \\
\hline\( + \) & \( - \) & \( +( \) at all \( T) \) & Reaction is non-spontaneous at all temperatures \\
\hline
\end{tabular}
Identify I, II, III in the above table.
I II III
(a) +ve \( \quad \)-ve (at low \( T \) ) Reaction is non-spontaneous at low temperature
(b) -ve \( \quad \) +ve (at low \( T \) ) Reaction is non-spontaneous at low temperature
(c) +ve -ve (at low \( T \) ) Reaction is spontaneous at low temperature
(d) -ve \( \quad \) +ve (at low \( T \) ) Reaction is spontaneous at low temperature
