Discusson Questions
For each graph, remember that the plot of volume vs. time represents the rate of the reaction, therefore the data with the steeper slope has the faster rate and the data with the more gradual slope has the slower rate. Answer the following set of questions based on YOUR graphs.
1a. For graph # 1 (Runs # 2, 3)
What was the varied factor ?
What were the constant factors ?
Which run # had the fastest rate
What was the value of the varied factor for the run with the fastest rate?
Which run # had the slowest rate ?
What was the value of the varied factor for the run with the slowest rate?
How did the varied factor affect the rates of the 3 runs >
Were the rate results as expected ?
Yes or no and EXPLAIN why.,
1b. For graph # 2 (Runs # 2, 4, & 5)
What What were was the the varied constant factor factors ? ?
Which run # had the fastest rate
What was the value of the varied factor for the run with the fastest rate?
Which run # had the slowest rate ?
What was the value of the varied factor for the run with the slowest rate ?
How did the varied factor affect the rates of the 3 runs ?
Were the rate results as expected ?
Yes or no and EXPLAIN why...
1c. For graph # 3 (Runs # 3 & 6)
What was the varied factor ?
What were the constant factors
Which run # had the fastest rate ?
What was the value of the varied factor for the run with the fastest rate?
Which run # had the slowest rate ?
What was the value of the varied factor for the run with the slowest rate ?
How did the varied factor affect the rates of the 2 runs ?
Were the rate results as expected ?
Yes or no and EXPLAIN why..
2. List the 6 values calculated for the quantity of reaction (vol H2 / mass Mg)
         Run #       Quantity of reaction          Run #   Quantity of reaction
1                                                             4
2                                                             5
3                                                             6
Are there any value(s) that stand out as being significantly different from the others If so, which one(s)?
The ideal value for the quantity of reaction should be .0 L/g That means 1.0 liter of H2 should be produced for every gram of Mg that is used in the reaction.
Are there any value(s) that are significantly different from the ideal value of 1.0 L/g If so, which one(s)?
Can you think of any experimental reason(s) that could account for the values being significantly different than the ideal value ?
3. Finally, discuss 3 4 specific sources of experimental error that could affect the results of this experiment. For each error, explain how it would affect the results of the experiment.
