QNEET-2017-Ch-923: NEET 2017 Chemistry - Class 11 NEET-2017-Ch-923 Solution: For a given reaction \( H = 35.5\ {kJ mol}^{-1}\) and \( S =…

For a given reaction

\Delta H = 35.5\ \text{kJ mol}^{-1}

and

\Delta S = 83.6\ \text{J K}^{-1}\ \text{mol}^{-1}

. The reaction is spontaneous at (Assume that

\Delta H

and

\Delta S

do not vary with temperature.) T > 425 K all temperatures T > 298 K T < 425 K

Step-by-Step Verified Solution

For a spontaneous reaction, _ G < 0 i.e. _ H - T _ S < 0 T > _ H _ S T > ( 35.5 _ 1000 83.6 = 424.6 � 425 K ) _ T > 425 K
