For the reaction between Iodine and propanone
I2 + CH3COCH3 + H+ --> CH3COCH2I + H+ + I-
The amount of Iodine is then titrated against standardised sodium thiosulphate :
I2 + 2Na2S2O3 --> 2NaI + Na2S4O6
How can i find out the reaction order with respect to I2,?????
i know is from a graph
but my graph is "vol of Na2S2O3 used against time at which the reaction was quenched."
