Current Question (ID: 21044)

Question:

$\text{Identify correct match using Column I \& Column II}$ $\begin{array}{|c|c|} \hline \text{Column I} & \text{Column II} \\ \hline \text{(i) Spontaneous process} & \text{(a) Isothermal and isobaric process} \\ \text{(ii) } \Delta H^\circ & \text{(b) } \Delta H < 0 \\ \text{(iii) } \Delta T = 0, \Delta P = 0 & \text{(c) } \Delta G < 0 \\ \text{(iv) Exothermic process} & \text{(d) (Bond energy of reactant) - (Bond energy of product)} \\ \hline \end{array}$

Options:

1. $\text{c d a b}$
2. $\text{b a c d}$
3. $\text{d b c d}$
4. $\text{a d b c}$

Solution:

$\text{Hint: Isothermal process temperature of a system remains constant}$ $\text{and isobaric pressure of a system remain constant.}$ $\text{(1)}$ $\text{(i) For spontaneous process } \Rightarrow \Delta G < 0$ $\text{(ii) For exothermic process } \Rightarrow \Delta H < 0$ $\text{(iii) For isothermal process } \Rightarrow \Delta T = 0$ $\text{For isobaric process } \Rightarrow \Delta P = 0$
