- 3. Two moles of an equimolar mixture of CO and H₂O (i.e., one mole of carbon monoxide and one mole of water vapor) is placed in an experimental reactor in which the water- gas shift reaction: CO(g) + H₂O(g) → CO₂(g) + H₂(g) occurs at 2 Atm and at a temperature at which 4G rxn= -0.6932RT. Determine the equilibrium composition (mole fractions) in the reactor.arrow_forward0.1 g of a sample of coal was used in a bomb calorimeter for the determination of calorific value. The ash formed was extracted with acid and the acid extract was heated with BaCl2 solution and a precipitate of BaSO4 was obtained. The precipitate was filtered, dried and weighed. The weight of precipitate was found to be 0.01 g. Calculate the percentage of sulfur in the coal sample.arrow_forward1 mol propane (C3H8) and stoichiometric amount of oxygen (O2) needed to combust propane was preheated to 400 K. After combustion, the products released are at 1500 K. The combustion products are H2O(l) and CO2(g). With 100% conversion was achieved, estimate the total heat released. Calculate the heat requirement for a reactor in combusting 1 mol of methane, CH4, with 25% excess air until the products reach a temperature of 1000 K. The reactants entered the reactor at 298.15 K and 100% conversion of methane is achieved. Assume air is approximately 21% O2 and 79% N2 and products are H2O(l) and CO2(g). Hint for both #1 and #2 – Combustion products at 298 K is CO2(g) and H2O(l). If the exiting temperature is above 373.15 K, H2O will leave as H2O(g). Therefore, you should account for the phase change of H2O(l) to H2O(g).arrow_forward

Cooling water, initially at 30 °C is continuously pumped through the reactor so that the outlet temperature is 748 °C and the core temperature remains constant. Calculate the rate of heat generated by the core of a nuclear reactor (in joules per second). (The specific heat capacity of ice 2100 Jkg 'K1; water = 4190 Jkg K; steam 2010 Jkg K. The latent heat of fusion of water is 334 kJ kg: latent heat of vaporisation of water 2264 kJ kg)arrow_forwardWhen the following gas reaction reaches equilibrium, at a certain temperature, the moles fractions of the four reactive species satisfy the following relation (we will use "y" for mole fractions since all of these reagents and products are gases): CO+H20 CO2+H2 K= [yCO2][yH2] [yco][yH20] Where K= 1. Assume that the feed introduced to the reactor is 2 mol of CO and 4 mol of H20 only. Also assume that the reaction reaches equilibrium. a) Calculate the extent of reaction in equilibrium (Šeg) b) Calculate the equilibrium composition, for this you need to calculate the mole fraction for all reactants and products.arrow_forward

HESS LAW (Law of Heat Summation) “The enthalpy change of the overall process is the sum of the enthalpy changes of the individual component steps.” - It is the standard enthalpy of Reaction, ΔHᵒ. - It can be illustrated in the following example Consider the following reactions: (a) Fe(s) + O2(g) à FeO(s)ΔHᵒ = -272 kJ (b) 2 Fe(s) + O2 (g) à Fe2O3(s)ΔHᵒ = -82.5 kJ 1. Make sure to write the balance equation. 2. The final equation requires 2 moles of FeO which means we will multiply equation (a) and its enthalpy change by 2. 3. Reverse equation (a), which means, the product goes to the reactant side, (2) (FeO(s) à Fe(s) + O2(g))ΔHᵒ = (-272 kJ)(2) = 544 kJ 2 FeO(s) à 2 Fe(s) + O2(g))ΔHᵒ = -825.5 kJ 4.
