Evidence: According to unit 15 packet there are 5 things that tdetermine reaction rate. One of them is concentration, adding more mater will increase the concentration. Reasoning: Increasing Concentration increases the rate of reaction because high concentration of reactant particles results in more effective collisions, which results in in a greater rate of reaction

So if you were to add an inhibitor to a reaction, you would cause the rate of reaction to decrease. The opposite idea of inhibitors are enzymes. These speed up chemical reactions, thus increasing the reaction rate. https://padlet.com/emilyumile/wt96zwu1geaewnt0/wish/520750324 2020-04-21 16:16:16 UTC https://padlet.com/emilyumile/wt96zwu1geaewnt0/wish/520750324 Owen McCormac https://padlet.com/emilyumile/wt96zwu1geaewnt0/wish/520753513 How does the catalyst and inhibitors affect the rate of chemical reaction?

The rapid removal of I₂ by ascorbic acid prohibits the formation of the black color. Once all of the ascorbic acid has been used up through, any I₂ formed will not be consumed and the black color appears. By adding varying amounts of ascorbic acid to otherwise identically prepared reaction mixtures, the time until the black color appears can be delayed to varying extents. A large amount of ascorbic acid produces a long delay, while a small amount yields a short delay.
