A. The starting concentration (time zero) of Crystal Violet Dye is 1 x 10-4 M. Calculate the concentration of crystal violet after 240 seconds. – Please include any equations used to determine your answer – Hint: Look at the Equation of the trend line for your most linear Graph and the Beer-Lambert Law?

B. Use the y-intercept from your straight line to obtain a value for ε, the Molar Absorptivity coefficient, for Crystal Violet Dye at time zero. – Please include any equations used to determine your answer – Hint: use the Beer-Lambert Law?

my y-intercept is y=.0004x-.5704
