Homework Equations
ln (V∞-Vt) = ln V∞ - k''t
Teacher Quote: "If ln (V∞-Vt) is plotted against t in a diagram a straight line will form with the k'' as the slope."
The Attempt at a Solution
I marked the t-values as X and ln(V∞-Vt) as Y and excel drew a plot that completely changed the values of Y, making them ten times as big to fit the X values.
