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 ...

especially if low concentration) Always refer to the rate of successful collisions, rather than the number of successful collisions. This is because, given enough time, even a slow reaction will ...

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- ...
