An improved Direct Reaction process which comprises reacting an organohalide with an activated silicon composition, the improvement comprising maintaining the composition of the activated silicon so that it comprises, based on the amount of silicon, 0.05-10 wt. % catalyst; an effective amount of promoter, and 0.001-0.1 wt. % tin, wherein the promoter to tin ratio is 10-250. Activated silicon compositions and methods for selecting a catalyst composition also are provided.
