Find k from half life
WebAnswer (1 of 19): If the half-life is short enough you simply measure it. You measure the radioactivity at some point, wait a little while, measure the activity again and mathematically calculate what the half-life is. It doesn’t have to be exactly a half because the ratio maintains the same. For... WebThat is why I spend more than half of my life exploring and looking to find a way to help people connect to themselves so they would be able to find their own self-esteem and confidence within them, so once and for all, they would be able to make their own steps at their own time. That is what I do. All the best to you, wherever you may go, Uriel

WebCalculate the half-life of a radioactive substance whose disintegration constant happens to be 0.002 1/years? Answer: the quantities available here are, λ = 0.002 1/years Consequently, the half life equation becomes: = 0.693/ λ = 0.693/0.002 = 346.5 Hence, the half-life of this particular radioactive substance is 346.5 years. Physics Formulas top windows free softwareWebFeb 12, 2024 · In order to solve the half life of first order reactions, we recall that the rate law of a first order reaction was: [A] = [A]oe − kt.
