Question

Did your experiment results in Data Table 3 verify, to within a reasonable experimental error, the condition of equilibrium of Equation 6: Στanti-clockwise = Στclockwise? Support your response with experimental data.

My data shows that they are not equal to each other.  So what does this mean?  Thanks!
