Effect of Concentration on Reaction Speed

Abstract

This study aimed to investigate the effect of concentration on reaction speed, so that we can find out more about the relationship between reaction rates and factors that influence reaction rates, namely temperature and the concentration of reagents. 10 test tubes are provided on the tube rack, 5 tubes filled with 5 mL H2SO4 (fixed concentration), 5 tubes filled with 5 mL, 4 mL, 3 mL, 2 mL, 1 mL Na2S2O3 0.1 M diluted to volume 5 mL with distilled water. Mix the contents of the tube from the first 5 preparations into the second preparation. The results show that the higher the concentration, the faster the reaction rate. Conversely, the lower the concentration, the slower the reaction rate.
