Let us consider an endothermic reaction which is non-spontaneous at the freezing point of water. However, the reaction is spontaneous at boiling point of water....

The standard enthalpy and standard entropy of decomposition of ${{\text{N}}_{2}}{{\text{O}}_{4}}$ to $\text{N}{{\text{O}}_{2}}$ are $55.0~\text{kJ}~\text{mo}{{\text{l}}^{{-1}}}$ and $175.0~\text{J}/\text{K}/\text{mol}$ respectively. The standard free energy change for this reaction...

Ice at $-{{5}^{{}^\circ }}\text{C}$ is heated to become vapor with temperature of ${{110}^{{}^\circ }}\text{C}$ at atmospheric pressure. The entropy change associated with this process can...

A liquid when kept inside a thermally insulated closed vessel at 25°C was mechanically stirred from outside. What will be the correct option for the...

Consider the following cases of standard enthalpy of reaction ( $\Delta \mathrm{H}_{\mathrm{r}}^{\circ}$ in $\mathrm{kJmol}^{-1}$ ) $$ \begin{aligned} & \mathrm{C}_2 \mathrm{H}_6(\mathrm{~g})+\frac{7}{2} \mathrm{O}_2(\mathrm{~g}) \rightarrow 2 \mathrm{CO}_2(\mathrm{~g})+3 \mathrm{H}_2...
