Given a list like this : lst = {a, b, c*t, r*s, 2*t, 3, 0}; I would like build a rule (c -> c t) for each elements c of the list that are not function of t that give like solution : Out[] := {a t, b t, c t, r s t, 2 t, 3 t, 0} I have tested the following way but they are not work lst /. (c_ /; FreeQ[c, t]) -> c*t and integrate[c_, t_] := c t /; FreeQ[c, t] lst /. c_ -> integrate[c, t] I will appreciate your held Guillermo Sanchez
