I'm taking grade 12 chemistry and there is a curve per the subject line and sorry to visually impaired but I need to paste an image as I'm not good at describing but it's basically looks like half a parabola that is in the top right quadrant concave to the right (if it were a parabola and does concave even make sense for curves?)
It says to find the rate of reaction at any point draw a tangent line but what if I can't? Ie. if the diagram is given on a test and is not drawn to scale, etc, that could be very difficult.
I looked at Khan academy on derivatives and this seems like something that I can get as as derivative but firstly I don't know what the equation of the line is but something similar to x^2? How would I get that instantaneous rate of change?
