When disorder of a system increases,the change is said to be

$A$ container has a hydrogen and oxygen mixture in a ratio of $4 : 1$ by weight. When these gases are mixed,which of the following occurs?

Let us consider a reversible reaction at temperature,$T$. In this reaction,both $\Delta H$ and $\Delta S$ were observed to have positive values. If the equilibrium temperature is $T_e$,then the reaction becomes spontaneous at:

In which state does matter have the highest entropy?

Entropy is maximum in case of

Calculate the entropy change when $1 \, \text{mole}$ of ice is converted into water at $0 \, ^\circ\text{C}$. (The enthalpy change for the conversion of ice to liquid at $0 \, ^\circ\text{C}$ is $6.0 \, \text{kJ} \, \text{mol}^{-1}$).
