Question

PLEASE EXPLAIN THE ANSWERS.

1. A sample was prepared by mixing 16 mL of 3.0 x 10-3 crystal violet (CV) with 4 mL of .250 M NaOH. Calculate the resulting concentrations of CV and OH-.

2. A student finds that the kinetics graphs are most linear for ln(CV) vs. time. The first trial, with 0.050 M NaOH, has a linear graph with the best-fit equation y= -0.00459x + 0.158. The second trial, run with 0.10 M NaOH, has a linear graph with the best-fit equation y= -0.00922x + 0.176. Based on these data, determine the overall rate.
