Hydrogen peroxide is used to disinfect porous surfaces like N95 masks by heating the liquid to 100C to make a vapor. Hydrogen peroxide liquid is stored as a 3.0% w/w solution at room temperature, but it quickly decomposes into water and oxygen in a first-order process. H2O2(aq) + H2O(l) + 1/2 O2(g) 4) If the initial concentration of Hydrogen peroxide is 0.52 M, what is the H2O2 concentration after 7.00 days? Use the equation In (X/Xf=kt a) 0.000012...

Hydrogen peroxide decomposes to water and oxygen gas. The rate law is -Δ[H2O2]/Δt=k[H2O2]. If a sample with an initial concentration of 0.151 mol/L has a concentration of 0.128 mol/L after 153 minutes, what is the rate constant?
1) Hydrogen peroxide, H2O2(aq), decomposes to H2O(l) and O2(g) in a reaction that is first order in H2O2 and has a rate constant k = 1.06×10−3 min−1 at a given temperature. How long will it take for 15% of a sample of H2O2 to decompose? 2)The decomposition of nitrogen dioxide, NO2, into nitrogen monoxide and oxygen at a high temperature is second-order in NO2. The rate constant for this reaction is 3.40 L/mol×min. Determine the time needed for the concentration...
Hydrogen peroxide (H2O2) decomposes as a first order reaction with a half-life of 17.2 minutes in the presence of a Fe(III) catalyst. How long would it take containing a 0.27 M H2O2 solution to become to a 0.027 M H2O2 solution after the Fe(III) catalyst is added?
Please show work I am not getting the correct answers 1. Hydrogen peroxide, H2O2, decomposes spontaneously through the following reaction. 2H2O2(aq) 2H2O(g) + O2(g) The kinetics are second order, and the half‐life is 17.3 min when a 1.75 M solution of H2O2 is made. What is the concentration of the solution after 24.8 min? 2. The decomposition of N2O5 occurs by the following reaction: 2N2O5(g) 4NO2(g) + O2(g) The rate constant is experimentally determined to be 3.4 x 10‐4 s‐1....
Hydrogen peroxide (H2O2) is a
possible product of the reduction of oxygen in acidic solution:
02(g)+2H+(aq) + 2 e-→ H2O2(,) H2O2(,) + 2 H+(aq) + 2 e-→ 2 H2O(aq) 02(g)+ 4 H+(aq)+4 e-→ 2 H20(,) E3 =0.70 V It can then be further reduced to water E2。 = 1.78 V The direct reduction of O2 to water has the following half-cell potential: E1 = 1.23 V (a) Compute ΔE° for the disproportionation of H2O2 in acidic solution. (b) Is H202...
Hydrogen peroxide decomposes spontaneously to yield water and oxygen gas according to the following reaction equation 24,0,(aq) → 2H0(i) +0,(8) The activation energy for this reaction is 75 kJ. mol. The enzyme catalase (found in blood) lowers the activation energy to 8.0 kJ. mol-1 At what temperature would the non-catalyzed reaction need to be run to have a rate equal to that of the enzyme-catalyzed reaction at 25°C?
