Webcalculate the mean rate of a reaction by using the equation: mean rate of reaction = quantity of reactant used time or quantity of product formed time A graph can be plotted to show how the quantity of product formed or the quantity of reactant used up changes with time. The gradient of the curve at a specific time indicates the actual rate of ... WebThe tangent drawn in the graph above shows that 72 cm 3 of product was produced in the first 20 seconds.Step 3: Calculate the gradient of the tangent (this will give you the initial rate of reaction): Gradient = change in y-axis ÷ change in x-axis. Initial rate of reaction = 72 cm 3 ÷ 20 s. Initial rate of reaction = 3.6 cm 3 s-1

WebIn summary, these graphs are similar to the 'product formed over time' graphs except the curve generally drops instead of increases! On a graph of rate over time, the shape of the curve will have a different meaning: A flat curve means the reaction rate is constant. Unless y = 0, the y axis staying constant shows that the reaction is still ... WebThis method only works if the formation of the precipitate is slow. The units for rate are usually /s (s-1) or /min (min-1). Graphs. The rate of reaction can be analysed by plotting a graph of mass or volume of product formed against time. The graph shows this for two reactions. The gradient WebData recorded in rate studies is used to plot graphs to calculate the rate of a reaction \n Time is normally plotted on the x-axis with the concentration of the reactant or product on the y-axis earthquake in pakistan today 2023
