$\Delta S$ is negative and $\Delta H$ should be highly positive

$\Delta S$ is negative and $\Delta H$ should be highly negative

$\Delta S$ is positive and $\Delta H$ should be negative

$\Delta S$ is positive and $\Delta H$ should also be highly positive

Explanation

To determine the correct statement for the spontaneous adsorption of a gas, we need to consider the thermodynamics involved. $\\$ The spontaneity of a process is determined by the Gibbs free energy change $(\Delta G). \\$ For a process to be spontaneous, $\Delta G$ must be negative. The relation is given by: $\\ \Delta G = \Delta H - T\Delta S \\$
