What is the enthalpy of reaction for C2H4 + 3O2 -> 2CO2+ 2H2O, if the conversion of CH4 is 50%, and heat of formation of CH4, O2, CO2, and H2O are 10 J, 0, 6 J and 4 J?

Correct Answer:
Heat of reaction = 2*4*0.5 + 2*6*0.5 + 10*0.5 – 0 – 10*0.5 = 10 J.

What is the heat of reaction for C2H4 + 3O2 -> 2CO2 + 2H2O, if heat of formation of C2H4, O2, CO2, and H2O are 10 J, 5 J, 6 J and 2 J respectively?

What is the enthalpy of reaction for CO2 + 4H2 -> 2H2O + CH4, if the conversion of CO2 is 50%, and heat of formation of CO2, H2, H2O, and CH4 are 6 J, 0, 4 J and 10 J?

What is the heat of reaction for CH4 + 2O2 -> CO2 + 2H2O, if heat of formation of CH4, O2, CO2 and H2O are 10 J, 5 J, 6 J, and 12 J respectively?

What is the heat of reaction for CH4 + 2O2 -> CO2 + 2H2O, if the heat of combustion of H2O = 5 J, CO2 = 10 J, O2 = 0, and CH4 = 25 J?

At a given temperature, K₁, K₂ and K3 are equilibrium constants for the following reactions 1, 2, 3 respectively.
CH₄(g) + H₂O(g) ⇋ CO(g) + 3H₂(g),
CO(g) + H₂O(g) ⇋ CO₂(g) + H₂(g)
CH₄(g) + 2H₂O(g) ⇋ CO₂(g) + 4H₂(g)
Then K₁, K₂ and K3 are related as:

A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:
