    How can you calculate the rate of reaction from graphs e.g, drawing tangents and finding initial rate of reaction?

    1. draw a tangent at the orgin
    2. calculate the gradient of the tangent -->Δy/Δx

    Thank you, does this work for all curved graphs and can you calculate it from any point?

    It depends which point it ask you for, the gradient changes in a curve.
    Each point has its own tangent, i am sure they will either state the x-value or ask for inital rate hope it makes sense:banana2:
