Physisorption is non-specific.Explain

Transcription starts non-specifically in the absence of

Which of the following statements is not true? a. Both physisorption and chemisorption are exothermic. b. Physisorption occurs with increase of free energy. c. Physisorption requires low activation energy but chemisorption requires high activation energy. d. The magnitude of chemisorption increases and that of physisorption decreases with rise in temperature.

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.
