This is the story of my life, i have been trying to solve this question, and i am not making any head way. It has really been very difficult for me to deal with. So please i need some one to please help me out with this question. Please give your honest solution. Thank you
You are expected to show all working clearly, to explain and justify your approach (eg calculation method or principles used to solve the problem) and this must be written in clear and unambiguou:s English. Aim your explanations at a scientifically literate person who is a non-expert in this topic. If you need to use diagrams, these may be neatly hand drawn and scanned in to the word document. (not photographed please) The reaction between hydrogen and oxygen is represented by the following simplified mechanism H2 + 02 2.OH H2OH 2) OH+ H2 3) ·H + .02. 4) . + H 5) H + O 6) ·H 8) HO2 .OH + .H â wall â wall â wall (a) At 750K, the system exhibits 3 explosion limits at pressures p1, P2 and p3 Explain why this is so in terms of brief discussion of the effectiveness of the various chain termination reactions at the following pressures i) below p1 i) between p1 and p2 ii) above p2 but below p3 (b) Assuming that reactions 6), 7) and 8) can be ignored above pressure p2, apply the steady state approximation to ,.Oand .OH radicals and obtain expressions for the steady state concentrations of H and .OH radicals (c) Derive an expression for the rate of formation of H2O and form this calculate the value of pz at 750K assuming k 2.81 x10 m3 mo s and ks 7.70 x 102 m6 mol2 s at this temperature. Hint; p2 is the pressure at which the reaction undergoes explosion- the rate is essentially infinite (d) Reaction 5) becomes an ineffective termination reaction and an explosion occurs above limit p3. Why is this?
