Drug remaining -50% 6.76% 20% This shows that in 2nd year the speed of reaction reverses and 2nd order reaction becomes slowest WebSep 24, 2024 · For a first order reaction we know that t 1/2 = 0.693/k. So, from the information provided, we can find the half life (t 1/2) and then plug it in to that equation. Fraction remaining = 0.5n where n = # of half lives that have elapsed. 0.20 = 0.5 n. log 0.20 = n log 0.5-0.699 = -0.301 n. n = 2.32 half lives. 2.32 half lives = 35.5 sec. 1 half ...
