What Was The Highest Concentration Value

The results support the hypothesis as the largest reaction rate value occurred when there was the highest concentration value. When the ratio between HCl: H2O was 10:0, HCl was not diluted and therefore had the highest concentration value. It was at this point as shown in Figure 2 that the time taken for the cross to disappear reached 94.5 s, which was the fastest speed. This is also illustrated because when HCl was most diluted at a concentration of 0.25, the time taken for the reaction to take place as shown in Figure 2 was 146.5 s, the slowest speed and in the table the lowest reaction rate.

The collision theory can also be used to explain this trend in the data. It states that for a chemical reaction to occur, the reactant particles must
