Rate of reaction of sodium thiosulfate and hydrochloric acid a first order or 2nd order reaction
Answers
Answer:
Sodium thiosulfate reacts with hydrochloric acid to form sulfur and sulfur dioxide (Equation 1).
Na2S2O3(aq) + 2HCl(aq) → S(s) + SO2(g) + 2NaCl(aq) Equation 1
The kinetics of the reaction can be analyzed by graphing the concentration of Na2S2O3 as a function of both reaction time and
1/time. A plot of concentration versus time gives a curved line, which levels off as it approaches the x-axis—the reaction slows
down as the reactant concentration decreases. The rate of a reaction is inversely proportional to reaction time. A plot of
concentration of versus 1/time gives a straight line. The rate is directly proportional to concentration, and the reaction appears
to be first order with respect to sodium thiosulfate concentration.
