In a particular case of physisorption, magnitude of enthalpy change and entropy change were observed to be 28 kJ/mole and 100 J/mole-K. Calculate the minimum temperature (in `.^(@)C`) above which physisorption will become non spontaneous.

For a reaction at 25^(@)C enthalpy change (DeltaH) and entropy change (DeltsS) are -11.7 K J mol^(-1) and -105J mol^(-1) K^(-1) , respectively. Find out whther this reaction is spontaneous or not?

At 300 K, the enthalpy change and entropy change of a reaction are -10 kcal and -30 " cal". K^(-1) respectively. Does the reaction occur spontaneously at 400 K ? If not, then calculate the maximum temperature at which the reaction will occur spontaneously ?

For a reaction at 25^(@)C enthalpy change (DeltaH) and entropy change (DeltaS) are -11.7 K J mol^(-1) and -105J mol^(-1) K^(-1) , respectively. Find out whether this reaction is spontaneous or not?

The enthalpy change for the transition of liquid water to steam Delta_("vap")H is 40.8 kJ mol^(-1) at 100^@C . Calculate the entropy change (Delta_("vap")S) for the process.
