The iodine clock reaction is a well-known and memorable chemical reaction where two colorless solutions are mixed and, after a period of time ranging from seconds to minutes, the solution suddenly turns from colorless to colored (yellow or bluish-black. Are doubled, the rate of chemical reaction will be increased by 4 since the reaction will still have the same rate constant, however, the rate expression will be changed into 'rate = k [2a][2b]' or 'rate = 4k [a][b]'.
