In a first-order reaction, the half-life is constant because it depends only on the rate constant, not the starting amount. It’s like my reactor feed concentration varies, but the time to drop to half is always the same on the control charts. For 99% completion, it takes about six to seven half-lives—you learn to be patient. Watching that decay curve reminds me of waiting for my daughter's college admission, a fixed timeline you can't rush no matter how much you worry.
