6. The decomposition of hydrogen peroxide is first order with respect to H₂O2. 2 H₂O2(1)→ 2 H₂O(l) + O2(g) The rate constant for this reaction at 293 K is 1.8 x 105 s. If the starting concentration of H₂O2 is 0.98M, how long it will take for the H₂O2 concentration to drop by 85%? A. about 4.6 x 104 s B. about 6.5 x 104 s C. about 1.1 x 105 s D. about 9.0 x 10³ s E. about 3.9 x 10³ s
