Claim: Adding water will increase the rate of reaction. 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

Owen McCormac-By definition, inhibitors slow down chemical reactions. 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.

Why did the solutions turn an orange color when stirred?

# data[].attributes.body
Claim- By adding small amounts of ascorbic acid to the reaction mixture, the appearance of the black color can be delayed because the ascorbic acid consumes any I₂ formed. 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.

David Polkowski: Claim -->Yes, color change will occur at a slower rate when not stirring. Evidence-->  When we did the lab using American Candy hearts, we exposed the hearts to an increase in temperature, (Kinetic Energy) and compared the solubility of that to American candy hearts exposed to an increase in temperature WITH stirring, our results showed an instantaneous solubility whereas the the candy heart exposed to only an increase in temperature had it's solubility slightly slower. Reasoning--> Stirring increase the rate at which a chemical reaction occurs in as a result, stirring keeps particles in motion. Therefore, having a higher probability of a change occurring.

The catalyst is a factor that can affect the rate of reaction (claim). A catalyst speeds up the rate of reaction by providing an alternate reaction pathway created by lowering the activation energy, therefore more reactions can occur (evidence).
-Emilio Yanez

Juan Amay:  A catalyst speeds up the rate of reaction by providing an alternate reaction

pathway created by lowering the activation energy. By lowering the activation energy there

are more effective collisions. This results in a greater the rate of reaction.

A catalyst increases the rates of both the forward and reverse reactions.

Reaction rate is calculated using the formula rate = Δ [C]/Δt, where Δ [C] is the change in product concentration during time period Δt.
