Question

1. My lab asked: The average deviation describes the precision of the results. Does the precision indicate that the equilibrium constant is indeed a “ constant ” for this reaction? Explain.
I said, "There is an average deviation of 5.2, however, if it wasn’t for experimental errors, the average deviation would be 0 and the value of equilibrium constant would be constant for each test solution."
Just wondering if this answers the question. If not, what changes should I make?

2. I have to interpolate the value of different concentrations from a graph. However, since interpolations can differ, can they count as errors in a lab? I was thinking those wrong interpolations will lead to incorrect calculations.
Thank You!!!

Explanation / Answer

1. Answer is perfectly correct.

2. Interpolations will not be calculated as error as long as it is clear from the graph which two points are used to draw the straight line.
