The rate of a reaction is plotted on a graph with time on the x axis and amount of product on the y axis. What would you expect the profile of the graph to look like?
Question
The rate of a reaction is plotted on a graph with time on the x axis and amount of product on the y axis. What would you expect the profile of the graph to look like?
Solution
The profile of the graph would typically look like a curve that initially rises steeply and then levels off as time progresses.
Here's why:
-
At the start of the reaction, the reactants are in high concentration, so the reaction rate is fast. This is represented by a steep upward slope on the graph.
-
As the reaction progresses, the concentration of reactants decreases, which slows down the reaction rate. This is represented by the slope of the graph becoming less steep.
-
Eventually, one or more of the reactants will be used up, stopping the reaction. At this point, the amount of product stops increasing, so the graph levels off.
-
The point at which the graph levels off represents the maximum amount of product that can be produced by the reaction. This is also known as the equilibrium point.
So, in summary, the graph would start at the origin (0,0), rise steeply at first, then less steeply, and finally level off.
