How can I analysis that a nanosheet -gas absorption process is exothermic and also found that electron is transferred from gas to nanosheet i.e Q>0. Is it possible?
As adsorption occurs, the change in the Gibbs energy of the process decreases. It occurs due to a decrease in the entropy of the gas and the exothermic reaction of the gas with the tubes. In order for the sign of the change in the Gibbs energy to be negative, the entopic contribution should be less than the entropic contribution. Thermodynamics does not provide information on the mechanism of the process and electronic transitions.
