Question

please do the graph1
Plotting results: (lab instructor will tell you what assignment is due for this lab exercise) Graph 1: each student should plot on one graph the amount of gas produced in each tube (dependent variable) vs. time of incubation (independent variable). The slope of the curve indicates the rate of the reaction -- the steeper the curve, the faster the reaction. Compare results with other teams and discuss sources of error. Graph 2: each student should plot on a second graph the amount of gas produced after 60 minutes incubation versus the average pH of the alcohol, and the buffering used may not quite be able to keep the pH constant. If the pH of any solution has changed during the experiment, use the average pH of that solution when you plot your results (Graph 2, below). All glassware must be thoroughly washed in hot soap solution and rinsed thoroughly. Replace tubes, etc. where you found them at the atart of the lab.

Answer 1

60 50 85 Nil 110 Nil 116 Nil 104 Nil 101 Nil 40 Time(min) Amount of gas produced/mm (TUBE 1) Amount of gas produced/mm (TUBE 2) Amount of gas produced/mm (TUBE 3) Amount of gas produced/mm (TUBE 4) Amount of gas produced/mm (TUBE 5) 0 0 0 0 10 10 15 25 20 25 37 53 35 30 30 53 72 85 65 52 102 84 80

Observation: Tube 3 has fastest reaction rate because it has steeper curve than others. It simply means, it produces more amount of gas / min than other reactions.
