What is the rate of consumption of O2 in a combustion reaction carried out in a 12.00 L flask if 7.42 mmol of oxygen is consumed in 13.9 s? Rate = 4.45e-5 Incorrect: Your answer is incorrect. M/s
Change in concentration of O2 = moles/volume
= 7.42×10-3/12 = 6.18×10-4 M
Rate of consumption = change in concentration/time taken
= 6.18×10-4/13.9
= 4.45×10-5 M/s

Part A Consider the combustion of H2(g):2H2(g)+O2(g)→2H2O(g). If hydrogen is burning at the rate of 0.51 mol/s, what is the rate of consumption of oxygen? Part B What is the rate of formation of water vapor? Part C The reaction 2NO(g)+Cl2(g)→2NOCl(g) is carried out in a closed vessel. If the partial pressure of NO is decreasing at the rate of 56 torr/min, what is the rate of change of the total pressure of the vessel?
As with any combustion reaction, the products of combusting a hydrocarbon fuel (CxHy) with oxygen (O2) are carbon dioxide (CO2) and water (H2O). A mass of 13.87 g for an unknown fuel was combusted in a reaction vessel containing an unknown amount of oxygen. At the end of the reaction, there still remained 13.80 g of the fuel as well as 0.1144 g of water and 0.2096 g of carbon dioxide. The oxygen was completely consumed during the reaction. How...
1. Calculate the standard enthalpy of combustion for the following reaction: C6H12O6 (s) + 6 O2 (g) ---> 6 CO2 (g) + 6 H2O (l) To solve this problem, we must know the following ΔH°f values: C6H12O6 (s) -1275.0 O2 (g) zero CO2 (g) -393.5 H2O (l) -285.8 5. 2. Using the reaction and ΔH from #1, calculate how many liters of oxygen gas will be used to produce 11,000 kJ of energy at 745 mmHg and 90°C.
The reaction N2(g)+O2(g)⇌2NO(g) is carried out at a temperature at which Kc = 0.050. The reaction mixture starts with only the product, [NO] = 0.0300 M , and no reactants.

Consider the reaction 4NO2(g)+ O2(g)→ 2N2O5(g) At a particular time during the reaction, nitrogen dioxide is being consumed at the rate of 0.0014 M/s. What rate is the molecular oxygen being consumed?
Under certain conditions the rate of this reaction is zero order in dinitrogen monoxide with a rate constant of 0.0014 M.sh: 2N20(g) → 2N2(g)+O2(g) Suppose a 2.0 L flask is charged under these conditions with 200. mmol of dinitrogen monoxide. After how much time is there only 100. mmol left? You may assume no other reaction is important. Be sure your answer has a unit symbol, if necessary, and round it to 2 significant digits. x 5 ?
16. The absorption coefficient of O2 in seawater at 0°C is 1.7 mmol/L. What is the concentration of O2 if the O2 partial pressure is 0.1 atm? Express your answer first in mmol/L, and then in mL/L. For this question, it is easy to get the mmol/L of oxygen. To convert mmol/L to mL/L, recall that dissolved gas is expressed as a volume of gas if it were removed from solution. So you need to use the ideal gas law...
