K= 1.54day-1
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...

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....

In a study of the decomposition of nitrosyl bromide at 10 °C NOBr—+NO+ Br2 the concentration of NOBr was followed as a function of time. It was found that a graph of 1/[NOBr] versus time in seconds gave a straight line with a slope of 1.27 m?s and a y-intercept of 3.98 M? Based on this plot, the reaction is order in NOBr and the rate constant for the reaction is M?? In a study of the decomposition of hydrogen...
