The heat change for the decomposition of 26.9 g of hydrogen peroxide (H2O2) is -145.31 kJ. What is the enthalpy of reaction (in kJ) for the process with respect to moles of hydrogen peroxide? Report your answer to 3 significant figures. Hint: Check the sign of your answer.
The decomposition of hydrogen peroxide in dilute sodium hydroxide at 20 °C H2O2(aq)H2O(l) + ½ O2(g) is first order in H2O2 with a rate constant of 1.10×10-3 min-1. If the initial concentration of H2O2 is 5.66×10-2 M, the concentration of H2O2 will be 9.34×10-3 M after _______ min have passed.
The decomposition of hydrogen peroxide in dilute sodium hydroxide at 20 °C H2O2(aq) ------> H2O(l) + ½ O2(g) is first order in H2O2 with a rate constant of 1.10×10-3min-1. If the initial concentration of H2O2 is 5.52×10-2 M, the concentration of H2O2 will be 1.56×10-2 M after _____ min have passed.
For the decomposition of hydrogen peroxide in dilute sodium hydroxide at 20 °C 2 H2O2(aq) 2 H2O(l) + O2(g) the following data have been obtained: 6.26x10-2 3.39x10-2 1.84x10-2 9.96x10-3 [H202], M time, min 9.28 18.6 27.9 The average rate of disappearance of H2O2 over the time period from t=18.6 min to t = 27.9 min is M min-1
In a study of the gas phase decomposition of hydrogen peroxide at 400 °C H2O2(g)----->H2O(g) + ½ O2(g) the concentration of H2O2 was followed as a function of time. It was found that a graph of 1/[H2O2] versus time in seconds gave a straight line with a slope of 0.884 M-1 s-1 and a y-intercept of 7.04 M-1. Based on this plot, the reaction is _______zerofirstsecond order in H2O2 and the rate constant for the reaction is M-1 s-1.
3. The decomposition of gaseous hydrogen peroxide to O2(g) and H2O(g) is a first-order reaction. Experimentally, at a given temperature, the initial concentration of H2O2 was found to decease to one- half in 17.0 minutes. What fraction of the initial H2O2 would remain after 51 minutes?
Hydrogen peroxide decomposes to water and oxygen: 2 H2O2 (1) + 2 H20 (1) + O2(g) Which solution would have a faster rate of decomposition: A solution of 3% H2O2 or a bottle of 30% H2O2?
Over time, hydrogen peroxide, H2O2, degrades into water and oxygen gas. A bottle of hydrogen peroxide is expired and you need to determine the concentration. A titration is performed using the following equation: 3 H2O2(aq) + 2 NaMnO4(aq) → 3 O2(g) + 2 MnO2(aq) + 2 NaOH(aq) + 2 H2O(l) Note that permanganate ion, MnO4-, is purple, while manganese (IV) ion, Mn4+, is colorless. A quantity of 683 mL of 3.44 M NaMnO4 was measured and placed in a beaker. The solution...
