Abstract We investigate the particle creation, as well as the thermodynamics phenomenon of viscous generalized cosmic Chaplygin gas as a cosmic fluid by assuming the flat FRW universe. For this purpose, we extract various parameters such as the energy density , Hubble parameter , declaration parameter , temperature , and particle number density in the presence of three different models of the particle creation rate ( ). We discuss the validity of the generalized second law of thermodynamics and thermal equilibrium condition under three models of and discuss the graphical behavior of above-mentioned terms.
