    okay so i have a conc vs time graph
    i need to a rate vs conc graph, in order to do this, i have to draw a tangent at each point, ive then drawn a line of best fit...the line does not go through all of the points...so how do i draw a tangent line of a particular point if the point is not touching the line of best fit?

    I'd say choose the closest point on the best fit curve (be it the one on top or below)
