my Ano hd Since we w After 50min, 14% of a compound has decomposed. Since we know that, K = - I en CAD - (Ao] = initial amount =100% CA] = (100-14)% = 86% 1 t = $50 min Since, from ean (i), K = - 1 an ( 86 ) *. al K = 6023 x 0 min I K = 3.02 x10–3 min 1 Since we know that, 0.693 ..!! . 0-693 3.02 x 103 min W HU ty2=229.47 min ty=22 9:5 min Anamera typ=229.5 min
