Question

x The chart below shows concentration vs. time data for the decomposition of hydrogen peroxide according to 2 H2O2(aq) -> 2H2000. Oxle) What is AH2021At from 434 minutes to 1302 minutes? Time (min) [H202] (M) 0 9.12 x 10 434 5.66 x 102 868 3.51 x 102 1302 2.18 x 102 Selected Answer: AH202 = 8.02 x 105 Mümin Answers AH202A - 100 x 105 min 1 ALH2021A - 2.00 x 10-SM min1 AH2O2A - 4.01 X 105 M min-1 A[H2O2A - 8.02 x 10 SM min-1

Answer 1

Given, Time (min) 2H₂O2 → 2H₂O + O2 [no] (M) & As ber Rate law 9:12x102 expression, 5.66X10-2 13-1 [H2O2) = + 1 A[HO] 2 dt 2 JA I 2.18x10-2 = + A[O) - 434 6x10-2 8 68 1302 3.51x10-2 Also, From oto 434 minir. So, for 434 to 1302 mint r = (5.66-9.12)x 102 ME-TX (2.18-5:66)x16 (434-0) (1302-434) = 3.96 x 10 m/min 1x4.01x10-5 so Hory A [H₂O2] =4.01.xloshminl At
