When an exothermic reaction produces a gas, what can be done to allow the reaction to continue to product once an equilibrium has been reached? Example: CH4 (g) + O2 (g) -> CO2 (g) + H20 (1) + Heat O Add more product O Apply more heat Reduce the amounts of reactants Remove gas to lower the pressure decrease the pressure

Hydrogen gas (a potential future fuel) can be formed by the reaction of methane with water according to the following equation: CH4(g)+H2O(g)?CO(g)+3H2(g) In a particular reaction, 25.5 L of methane gas (measured at a pressure of 736 torr and a temperature of 25 ?C) is mixed with 22.6 L of water vapor (measured at a pressure of 700 torrand a temperature of 125 ?C). The reaction produces 27.0 L of hydrogen gas measured at STP. What is the percent yield...

ynthesis gas, a mixture that includes the fuels carbon monoxide and molecular hydrogen, is used produce liquid hydrocarbons and methanol. It is made at pressures up to 100 atm by oxidation of methane followed by the steam re-forming and water-gas shift reactions. Because the is exothermic, temperatures reach 950 1100°C, and the conditions are such that the amounts of hydrogen, carbon monoxide, carbon dioxide, methane and water leaving the reactor are close to the equilibrium amounts for the steam re-forming...

Flue gas from a furnace is 30 mol% SO2, 25 mol% O2, and remainder CO2. To clean 1155 mol/hr of flue gas and remove SO2, it is to be reacted with pure methane (natural gas) such that for every 65 moles of SO2 in the flue gas, 67 moles of methane is used (supplied). The primary reaction between methane and SO2 is as follows CH4 + SO2 → H2S + CO2 + H2O A side reaction also occurs as...

Methane (CH4) and oxygen (O2) react to form formaldehyde (CH2O) (reaction #1), with a competing side reaction (#2) in which methane and oxygen form carbon dioxide (CO2): CH4(v) + O2(g) -> CH2O(v) + H2O(l) (reaction #1) CH4(v) + 2O2(g) -> CO2(g) + 2H2O(l) (reaction #2) A fresh feed of an equimolar gas mixture of CH4 and O2 is combined with a recycle stream and fed to a reactor. The single-pass conversion of CH4 is 30% and the selectivity of CH2O...
