For the given reaction CO2 + 4 H → CH2O + H2O In the feed there are 4 moles of CO2, 10 moles of H. If the reaction happens then 8. What is the number of moles of the extent reactant in the reaction after completion?

Correct Answer: 1.5
Number of moles of CO2 left = 4 – 2.5 = 1.5.

A reactor is supplied with 5 moles each of CH3OH and O2, and the following reactions occur, CH3OH + 1/2O2 -> CH2O + H2O and then CH2O + 1/2O2 -> CO + H2O, the conversion of methanol is 80% in first reaction, and conversion of CH2O is 50% in second reaction. How many moles of CH2O came out of the reactor?

For the given water gas reaction, CO + H2O → CO2 + H2 The feed consists of 18 moles of CO and 20 moles of steam. In the product, both CO2 and H2 are 15 moles. 6. Which is the limiting reactant in water gas reaction?

Rate constant for a first order reaction does not depend upon reaction time, extent of reaction and the initial concentration of reactants ; but it is a function of reaction temperature. In a chemical reaction, the time required to reduce the concentration of reactant from 100 gm moles/litre to 50 gm moles/litre is same as that required to reduce it from 2 gm moles/litre to 1 gm mole/litre in the same volume. Then the order of this reaction is

A reactor supplied with CO2 and H2O, the product contains CO2, H2O and H2CO3, if the rate of products is 10 mole and percentage of CO2 in products is 20%, what is the feed rate of H2O?

The reaction between ethylene and hydrogen bromide to form ethyl bromide is carried out in a continuous reactor. C2H4 + HBr = C2H5Br The product stream is analyzed and found to contain 51.7 mole% C2H5Br and 17.3% HBr. The feed to the reactor contains only ethylene and hydrogen bromide. Calculate the fractional conversion of the limiting reactant and the percentage by which the other reactant is in excess. If the molar flow rate of the feed stream is 165 mol/s, what is the extent of reaction?

For a reaction, the extent of reaction equation is Ni = Nio + ϒVi is Where: Ni = Moles of species I present in the system after the reaction occurs Nio = Moles of species I present in the system when the reaction starts Vi = Stoichiometric coefficient for species i in the specified chemical reaction equation ϒ = Extent of reaction
