activity coefficent

what is the activity coefficient value of H+ ions for the reaction of an arrenshius acid wth iodide in the presence of iodate, a catalyst to from hydrogen ion iodine and water. l think the coefficient is 0.927 but from  my calculation  its wrong

Activity coefficient depends on the ionic strength of the solution, which in turn depends on concentrations of all ions present in the solution - reaction doesn't matter.
