Q2NEET 2025Q.85Medium
The standard heat of formation, in kcal/mol of $\ce{Ba^2+}$ is:
[Given: standard heat of formation of $\ce{SO4^2-}$ ion (aq) = −216 kcal/mol, standard heat of crystallisation of $\ce{BaSO4(s)}$ = −4.5 kcal/mol, standard heat of formation of $\ce{BaSO4(s)}$ = −349 kcal/mol]
$\ce{Ba^2+}$ की मानक संभवन ऊष्मा, kcal/mol में, है:
[दिया है: $\ce{SO4^2-}$ आयन (aq) की मानक संभवन ऊष्मा = −216 kcal/mol, $\ce{BaSO4(s)}$ की मानक क्रिस्टलन ऊष्मा = −4.5 kcal/mol, $\ce{BaSO4(s)}$ की मानक संभवन ऊष्मा = −349 kcal/mol]
