    During adsorption, the signs of \[\Delta H\], \[\Delta S\] and \[\Delta G\] are respectively:

    A)  \[-,-,+\]                              

    B)  \[+,+,-\]

    C)  \[-,+,-\]                              

    D)  \[-,-,-\]

    Correct Answer: B

    Solution :

                    Adsorption is an exothermic \[(\Delta H=-ve)\]and spontaneous  \[(\Delta H=-ve)\]  phenomenon. During this process randomness of molecules decreases and consequently entropy decrease \[(\Delta H=-ve)\]
