A gaseous fuel is a mixture of equal parts by volume of carbon monoxide and methane (CH4) The gas burns with a quantity of air which is 20% greater than the stoichiometric amount. The products of Combustion, which contain only CO2, CO, H2O, H2, O2 and N2, are in equilibrium when they are discharged at atmospheric pressure. If the carbon monoxide If the carbon monoxide content of the content of the exhaust is not to exceed 1% by volume, show that the temperature of the exhaust must not be greater than 2,360°K approximately. Calculate also the hydrogen content of the exhaust.
At 2,360°K the equilibrium constants, based on a reference pressure p0 of one atmosphere, have the values
Both equilibrium constants decrease with increasing temperature. Air contains 21% oxygen by volume.
If the concentration of X is increased to 2.0 M and the concentration of Z to 3.0 M, how long should this reaction take?
a -gt b 2c this is the elementary gas-phase reaction that is carried out isothermally in a flow reactor without any
Explain how much 3M NaOH MW=40 can be made from 10.0ml of a 10M solution
Explain a sample weighing 3.073 g is a mixture of Fe2O3 molar mass = 159.69 and Al2O3 molar mass = 101.96. While heat and a stream of H2 gas is applied the to the sample the Fe2O3 reacts to form metallic Fe and H2O(g).
