How Do You Work Out The Tangent On A Rate Of Reaction Graph?
Okay, I’m not sure, but this is my best guess: Firstly a tangent, is a straight line that touches a curve at a point (but only touches it, and doesn’t cross it) Usually you draw a tangent to the line of a distance/time graph or something where the line is curved (if the distance journeyed isn’t directly proportional to the time spent) to find the instantaneous speed of an object (like, the speed of an object at a single moment in time, not the average speed) So usually a ‘tangent’ is drawn so that it’s touching a curve, and you find the gradient to find the ‘gradient’ of that point on the curve. But, if you’re drawing a line of best fit, it sounds like you’re drawing a straight line, so the amount of gas produced is ‘directly proportional’ to the time that’s passed. And, presuming the ‘rate of reaction’ is the line you’ve drawn based on your results, then I think you just need to calculate the gradient (gradient = the change in y divided by the change in x) But if I’m wrong and your li
