  A flat FLRW cosmological model with perfect fluid comprising of variable
Chaplygin gas has been studied in context of f(R; T) gravity with particle
creation. The considered scale factors describe the accelerated expansion of
universe due to the effective negative pressure produced during evolution of
universe. The role of particle creation pressure on the cosmological parameters
have been discussed in detail. By considering well accepted values of free
parameters, the late time expansion of the universe with energy conditions have
also been studied. The state-finder diagnostic for the considered cases have
been studied and the evolution of source function with time have suggested
almost constant particle production at late times.
