t1/20-a, t1/2(5)For thethen i(1) 10 min; 20 min(3) 25 min, 50 minFor an elementarzero order reorder reaction A B + C, initial concentration of A is 0.1 M. If [A]- 0.08 M after 10 minutest's half -life and completion time are respectively(2) 2 x 10-3 min; 4 x 103 min(4) 250 min, 500 min |
Answer» for zero order reaction the formula for conc. at time t is Ct = C°-kt 0.08 = 0.1 -k(10) => k = 0.02/10 = 0.002M/min now half life is when the conc. of A = 0.05M so t = 0.05/k = 0.05/0.002 = 25min. and completion time is 2times the half life. = 50min. option C. |
