As the rate is changing throughout the reaction, we are calculating the average rate over a given time period. For example, the graph below could be used to calculate the average rate over any ...

If the concentration is increased: there are more reactant particles there are more successful collision per unit time the rate of ... solution), the graph line for the same reaction but at ...

The different lengths of time needed to achieve the starch/iodine complex shows the effect of temperature on reaction rates. Reactions A1-A3 dominate (A3 is very fast) until all HSO3- is consumed. I3- ...
