1. Suppose that the formation of mullite from a mixture of alumina and silica powders is a diffusion-controlled process. How would you prove it? If the activation energy is 50 kcal/mole and the reaction proceeds to 10% of completion at 1400°C in 1 hour, how far will it go in 1 hr at 1500°C? and in 4 hr at 1500°C? Answer: 0.15, 0.284.

In a sample digested with phosphoric acid, it was found that analysis of calcium reflects less sensitivity than when digestion is done with hydrochloric acid. Explain.
Please answer the following with complete solution. Thank you. A mixture placed in an Erlenmeyer flask comprises 6mL of silica gel and 40mL of a solvent containing, in solution, 100mg of a non-volatile compound. After stirring, the mixture was left to stand before a 10mL aliquot of the solution was extracted and evaporated to dryness. The residue weighed 12mg. Calculate the adsorption coefficient, K=CS/CM, of the compound in this experiment.
The procedure for the synthesis of menthone indicates that you should use 10 cm³ of 6M sulphuric acid. Suppose that only sulphuric acid with concentration 1.5M is available in the laboratory. What volume in cubic centimetres of this solution do you need to add to the reaction mixture to replace the solution originally specified?
A sample of an iron ore was prepared for Fe3+ analysis as following: 3.4g of the sample was added anddissolved in acid environment then diluted to 250 mL using volumetric flask. After that, 10 mL of the resultingsolution was transferred by pipet to a 50-mL volumetric flask and continue to be diluted. The scientists foundout that this solution gives the concentration of Fe3+ as 2.3 mg/L. Find the weight percentage of Fe3+ in theoriginal sample.
For each of the following statements, answer True or False and explain your answer briefly. It is preferred to apply colour tests, as a screening test, over microcrystalline tests in drug analysis.

Which statement is true? Statement 1: In a paper chromatography that uses a cellulose-based filter paper as stationary phase and hexane as the mobile phase, non-polar compounds are expected to have higher Rf values than that of polar compounds. Statement 2: In paper chromatography, the highly adsorbed compounds tend to outdistance the weakly adsorbed ones.
For each of the following experiments, try to identify the major probable sources of random and systematic errors, and consider how such errors may be minimized: 1. The iron content of a large lump of ore is determined by taking a single small sample, dissolving it in acid, and titrating with ceric sulphate after reduction of Fe (III) to Fe (II). 2. The same sampling and dissolution procedure is used as in (a) but the iron is determined colorimetrically after addition of a chelating reagent and extraction of the resulting colored and uncharged complex into an organic solvent. 3. The sulphate content of an aqueous solution is determined gravimetrically with barium chloride as the precipitant.
