Half life equation calc
WebIn this problem, we are given that it takes 444 years for the substance to lose 1/2 of its radioactive nuclei, so in each year, it will tick through only one-444th of its half-life. So our exponent is t/444. We then can say that N (t) = N₀ (1/2) ^ (t/444) You asked what the constant value is for mercury 194. WebThe rate for second order reactions is rate = k [A]2, so it decreases exponentially, unlike first order reactions. The rate law is 1/ [A] = kt + 1/ [A]0 and the equation used to find the half-life of a second order reaction is t1/2 = 1 / k [A]0 . Where. k is the temperature-dependent reaction rate constant. t 1/2 is the half life.
