For the reaction $NH_4Cl_{(s)} \rightarrow NH_{3(g)} + HCl_{(g)}$,the entropy change is ...... .

Which of the following reactions will have the value of $\Delta S$ with a negative sign?

What is meant by absolute entropy?

For chemical reactions,the calculation of change in entropy is normally done:

Maximum entropy will be in which of the following?

What is the entropy change (in $J\, K^{-1}\, mol^{-1}$) when one mole of ice is converted into water at $0^{\circ}C$? (The enthalpy change for the conversion of ice to liquid water is $6.0\, kJ\, mol^{-1}$ at $0^{\circ}C$)
