Reaction Lab

The experiment began with a reaction of a 1cm3 cube of lamb liver and 5mL of hydrogen peroxide solution being put in test tubes in a beaker filled with 10℃ water until the temperatures of the liver and hydrogen peroxide were 10℃ also. The liver was put into a 100mL measuring cylinder and the hydrogen peroxide was also poured in as the timer was started. After twenty seconds, several millilitres of froth had been produced from the chemical concoction. This froth was recorded into a results table, and the previous steps were repeated but with increasing temperature increments of 10℃ until 50℃. After carefully completing the experiment, the final results obtained by measuring the volume of the froth produced after 20 seconds, were recorded in a table - see Table 1, and able to be observed in a graph, see Figure 7. The rate of reaction was recorded in Table 1 and graphed in Figure 8.

From 10oC to 20oC, the average rate of reaction of the class results is higher than the raw results rate of reaction by a maximum of 0.75mL/sec. However, from 30oC to 50oC, the raw results presented a slightly higher lot of rate of reaction than the average rate of reaction from the class results. The highest rate of reaction difference was for 50oC, with a difference of 0.3mL/sec between the raw and average results. This information supports the hypothesis, yet the result for 10oC and 20oC do not support the hypothesis, as due to the information known about enzymes, the lower the temperature, the slower the rate of reaction should be, therefore the average rate of reaction does not support the
