Half life chem problems
WebSo for the first half-life, the first half-life is say time would be 5 seconds. That means the second half-life would also be another 5 seconds. The third half-life would be another 5 seconds, fourth half-life would be another 5 seconds. So after 4 half lives, then the total would be 20 seconds that you have there. WebDetermining a Half Life. To determine a half life, t ½, the time required for the initial concentration of a reactant to be reduced to one-half its initial value, we need to know: The order of the reaction or enough information …
