Some reactions such as ionic reactions occur very fast, for example,
precipitation of silver chloride occurs instantaneously by mixing of
aqueous solutions of silver nitrate and sodium chloride On the other
hand, some reactions are very slow, for example, rusting of iron in
the presence of air and moisture Also there are reactions like inversion
of cane sugar and hydrolysis of starch, which proceed with a moderate
speed Can you think of more examples from each category
