    Does anyone know how to work out the initial rate of reaction?? I know it is x/y but on a graph which is distance on the y axis and time on the x axis what would you do?? Is it for example 15mm / 30 seconds (thats my first time reading) OR do you just read off from the 30 seconds, go up to the point on the line of best fit and say that the initial rate of reaction is 15 seconds and you do not divide at all. I am so confused!!! Help cuz i need to make an initial rate of reaction graph!!!

    not really sure what you mean but for starters, have you got time on the x axis?
    I think you do just do x/y but i'm not sure.
    We never had to do an initial rate of reaction graph

    Speed = Distance / Time

    I can't possibly see how you graph relates to rate of reaction. :confused:

    Also, you have to work out the gradient of the graph

    Gradient = Change of y-axis / Change of x-axis

    If you have a curve you must work out the tangent of the graph.
