Subje ct: Proce ss Calc ulations
Tutorial Sheet No. 2 Prob 1 I n the reaction in which 1 moles of methane and 45.0 moles of oxyg en are fed into a 35 reactor, if the reaction g oes to completion, calculate the extent of reaction. 6 CH4 + O2 = 2 C 2H2 + 2 CO + 1 H2 0 Prob. 2 Antimony is obtained by heating pulverized stibnite ( Sb 2 S3 ) with scrap iron and drawing off the molten antimony from the bottom of the reaction vessel Sb2 S 3 + 3 Fe = 2 Sb + 3 F eS Suppose that 0.600 kg of stibnite and 0.250 kg of iron ore turning are heated tog ether to g ive 0.200 kg of Sb metal. Determine ( a) The limiting reactant ( b) The percentage of excess reactant ( c) The degree of completion ( d) The percentage conversion based on Sb2 S 3 ( e) The y ield of k g Sb produced/ kg Sb 2S 3 fed to the reactor. Prob.3 A common method used in manufacturing sodium hypochlorite bleach is by the reaction C l2 + 2 NaOH = NaC l + NaOCl + H2 O C hlorine gas is bubbled through an aqueous solution of sodium hydroxide, after which the desired product is separated from the sodium chloride ( a by product of the reaction). A water NaOH solution that contains 520.5 k g of pure NaOH is reacted with 386.8 k g of g aseous chlorine. The NaOC l formed weighs 280.9 k g. (a) What was the limiting reactant? ( b) What was the percentag e excess of the excess reactant used? ( c) What is the deg ree of completion of the reaction, expressed as the moles of NaOC l formed to the moles of NaOCl that would have formed if the reaction had gone to completion? ( d) What is the y ield of NaOCl per amount of Chlorine use ( on weig ht basis)? (e) What was the extent of reaction? Prob.4 I n a process for the manufacture of chlorine by direct oxidation of HC l with air over a catalyst to form Cl2 and H2O ( only), the exit product is composed of HCl (4.4% ), Cl2 ( 19.8% ), H2O ( 19.8% ), O 2 ( 4.0% ) and N2 (52.0% ). What was ( a) the limiting reactant ( b) the precent excess reactant? ( c) the degree of completion of the...
