How do you work out the inital rate of reaction from looking at graphs?
Ulex says I am assuming you are looking at a graph of reactant concentration plotted against time. The graph will be a curve going down to the right. The initial rate of the reaction is the gradient of this curve at its top right-hand end (i.e. when time =0). Draw a tangent to the graph at this point and find the gradient of it. This, ignoring the minus sign, is the initial rate of the reaction. Risk assessment Before attempting any practical work based on the advice and suggestions on this website, you must do the following. Identify any hazards, assess the risks from these hazards, and then decide appropriate control measures to reduce the risks. You must have these approved by those in authority in your school or college laboratory. Do not rely on what is said on this website. For further guidance see our tutorial on Risk Assessment.
