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 ...

JON CHASE:'There four methods of increasing the rate of reaction. 'My mate Professor Seller is going to talk me through them. JON CHASE:'First up - concentration.' PROFESSOR SELLER:What we're ...

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- ...

After a few seconds, the disappearance of yellow dye with the more concentrated bleach solution can be observed, followed after several seconds by the more dilute bleach reaction. Complete ...
