Ion acoustic solitary waves in three-component plasmas with isononthermal electron, positron and ion are studied using Sagdeev Pseudopotential method. Trapping parameter (beta), the ratio of the temperatures of the free and trapped electrons, is treated as a variable. We study effect of (beta) on speed of solitons.
