In an experiment (reaction between acetone and iodine under acidic conditions), initial conc of iodine = 0.00455; initial concentration of H+ = 0.0455, and initial concentration of acetone is unknown. After 5 min intervals, reaction mixture is titrated against 0.0005 M thiosulfate solution. After calculating concentration of iodine remaining at time=t, i plotted a graph of concentration of iodine against time which is a straight line graph. Rate of reaction is zero order w.r.t iodine but orders w.r.t acetone and H+ are unknown. The slope of the graph = rate constant. But i'm confused, is it the same rate constant that can be plugged into the equation: rate = K [acetone]^m [H+]^n ? And will rate be equal to the rate constant K?

I hope you understand what I mean :/
