WebSep 5, 2024 · (extended). This allows us to use a graph to predict values which lie outside the range of the available data. The line of best fit could also be a curve. A curve is common in rates of reaction graphs. A straight line would indicate a constant rate of reaction, while a curve indicates a change in the rate (or speed) of a reaction over time. If ...

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 ...
WebFor example, the graph below could be used to calculate the average rate over any period of time Using this graph, we can calculate the average rate between 30 seconds and … WebThere are several factors that can affect the rate of a reaction. These are: Concentration of the reactants in solution or the pressure of reacting gases; Temperature at which the reaction is carried out; Surface area of solid reactants; The use of a catalyst; Changes in these factors directly influence the rate of a reaction
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 ...
WebFeb 24, 2024 · The average rate of reaction is just what we said before: (change in reactant)/ (time) = -10.5 g of A/25 s = -0.42 g of A/s; this is just the slope of the red line. So, for every second, 0.42 g of ...
