Two statements are given below
Statements I : Liquids $A$ and $B$ form a non-ideal solution with positive deviation. The interactions between $A$ and $B$ are weaker than $A-A$ and $B-B$ interactions.
Statements II : For an ideal solution $\Delta_{\text {mix }} H=0$; $\Delta_{\text {mix }} V=0$
The correct answer is
At 300 K , the $E_{\text {cell }}^{\ominus}$ of
$$ A(s)+B^{2+}(a q) \rightleftharpoons A^{2+}(a q)+B(s) $$
is 1.0 V . If $\Delta_r S^\theta$ of this reaction is $100 \mathrm{JK}^{-1}$. What is $\Delta_r H^{\ominus}$ (in $\mathrm{kJ} \mathrm{mol}^{-1}$ ) of this reaction?
$$ \left(\mathrm{F}=96500 \mathrm{C} \mathrm{~mol}^{-1}\right) $$

Two statements are given below
Statements I : Adsorption of a gas on the surface of charcoal is primarily an exothermic reaction.
Statement II : A closed vessel contains $\mathrm{O}_2, \mathrm{H}_2, \mathrm{Cl}_2$, $\mathrm{NH}_3$ gases. Its pressure is $p$ (atm). About 1 g of charcoal is added to this vessel and after some time its pressure was found to be less than $p$ (atm)
The correct answer is
