(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2HCl + Na_{2}S_{2}O_{3}-> 2NaCl +S + SO_{2}+ H_{2}O

Find the order of reaction with respect to S_{2}O_{3}^{2-}and H^{+}

volume of 3.0M HCl was held constant at 2ml

2. Relevant equations

S_{2}O_{3}^{2-}+ 2H^{+}-> S + SO_{2}+ H_{2}O

rate = k[Na_{2}S_{2}O_{3}]^{m}[HCl]^{n}(see number 3.)

3. The attempt at a solution

i just started taking calculus so I'm having a hard time understanding most of the equations I find in the net and most of them skip the part of solving so I can't find enough examples.

I tried to graph the S_{2}O_{3}^{2-}part first

Concentration of reaction against time(left)

Rate of Reaction against Concentration of a Reactant(right)

it "looks" like the graph of a second order. could someone please tell me if it is correct and another way of solving it aside from graphing and some calculus? thanks in advance
