;)Hi there!

 

I am doing a coursework on the practical 'kinetics of the reaction between iodine and propanone in acid solution' however I cannot find anything on the internet stating the litrature value for the order of reaction for Iodine, please would you advise me what to type to get this value.Could you leave the address of where you found it.

Also, the graph obtained by plotting the 'titres of E' against time is looks a like it could be a curve or a straight line. How do I decide which one is correct?

Thirdly, does this graph I have plotted represent the order of reaction for Iodine, OR must I change the graph in order to find the order out.

 

Thankyou

-Plot the [math] [i_2 ] [/math] versus time. If this gives a linear plot, the reaction is zero order with respect to iodine.

 

-Plot [math] ln[i_2 ] [/math] vs time...if linear, the reaction is first order with respect to iodine.

 

-Plot [math] \frac{1}{[i_2 ]}[/math] vs.time...If linear, 2nd order reaction

 

If you have a rate constant and an observed rate for the reaction, you can just solve for the individual reactant orders algebraically with logarithms.
