Sodium thiosulphate and order of reaction Watch
if this is for edexel, you usually have a table of values for the rate or time with the conc of reagents, if the rate doubles when the conc of one of the reagent doubles the order for that reagent is 1
if the conc doubles but the rate quadruples the order of that reagent is 2
if there's no change inthe rate for the doubling of the conc of a reagent, the order of the reaction is 0
adding all the orders in a reaction will give you the overall rate
does that help at all? (hope im not telling you what you already know lol)
I initially wanted to know the order of reaction of the equation between Na2S203 and HCl. I conducted this experiment at a HCL concentration of ~0.5M. This provided me with the order of reaction with respect to HCL being zero. I reconducted this experiment with HCL conc at 2M. This lead to an order of 2 (with respect to HCL). Markkey about also commented on the variance of order with concentration. I wish to know how the concentration changes the order of the reaction (with HCL)?
