Vedclass · Answer

(B) The enthalpy changes for the given processes are as follows:$1$. $O_{(g)} 	o O^{+}_{(g)}$: This is the first ionization enthalpy of oxygen,which is a large positive value $(+1314 \ kJ/mol)$.$2$. $O_{(g)} 	o O^{-}_{(g)}$: This is the electron gain enthalpy of oxygen,which is negative $(-141 \ kJ/mol)$.$3$. $O^{+}_{(g)} 	o O^{2+}_{(g)}$: This is the second ionization enthalpy of oxygen,which is a very large positive value $(+3388 \ kJ/mol)$.$4$. $S_{(g)} 	o S^{-}_{(g)}$: This is the electron gain enthalpy of sulfur,which is negative $(-200 \ kJ/mol)$.Comparing the magnitudes of enthalpy change,the process $O_{(g)} 	o O^{-}_{(g)}$ involves the release of $141 \ kJ/mol$,while $S_{(g)} 	o S^{-}_{(g)}$ involves the release of $200 \ kJ/mol$. The process with the least enthalpy change (smallest absolute value) is $O_{(g)} 	o O^{-}_{(g)}$.
