complex reactions and reaction sequences‚ where raw materials react together to give the product. Such chemical process often releases energy‚ in the form of heat‚ and the reaction is described as exothermic. Many of these reactions may also evolve gases at high rates‚ and could cause reactor over-pressure. Thermal runaway reaction Runaway reactions are thermally unstable reactions where the heat of reaction can raise the temperature of the reactants sufficiently to accelerate the reaction rate out

Elimination Reactions ________________________________________ As described previously‚ primary alkyl halides generally undergo substitution reactions with simple nucleophiles by an SN2 mechanism. Secondary alkyl halides‚ often react with simple basic nucleophiles to give a mixture of products arising from both substitution and elimination. As with substitution reactions‚ the rate at which elimination reactions proceed can be proportional to both the concentration of the base and the concentration

My Reaction to Apollo 13 The movie Apollo13 is great but little kind of boring. Tom Hanks is a great artist! He is my idol. One of his great movie is Forrest Gump. By the way‚ The Apollo13 is America’s third moon landing mission. En route‚ an onboard explosion deprives their spacecraft of most of its oxygen supply and electric power‚ forcing NASA’s flight controllers to abort the Moon landing‚ and turning the mission into a struggle to get the three men home safely. I thought Jim’s wife was his

His book on the war‚ Vietnam Inc.‚ crystallized public opinion and gave form to Western misgivings about American involvement in Vietnam. One of the most detailed surveys of any conflict‚ Vietnam Inc. is also an in-depth document of Vietnamese culture under attack. An associate member of Magnum since 1966‚ Griffiths became a member in 1971. In 1973 he covered the Yom Kippur War and then worked in Cambodia between 1973 and 1975. In 1977 he covered Asia from his base in Thailand. In 1980 Griffiths

I wake up fine and dandy but then by the time I find it handy‚ To rip my heart apart and start planning my crash landing‚ I go up‚ up‚ up‚ up‚ up to the ceiling‚ Then I feel my soul start leaving‚ like an old man’s hair receding‚ I’m pleading please‚ oh please on my knees repeatedly asking‚ Why it’s got to be like this‚ is this living free‚ I don’t want to be the one‚ be the one who has the sun’s blood on my hands‚ I’ll tell the moon‚ take this weapon forged in darkness‚ Some see a pen‚ I see a harpoon

ENGINEERING Reaction Engineering CGC035 / CGC052 Problem Sheet 3 - Fluid-fluid reactions 1. The reaction rate for the heterogeneous reaction A(g) + B(l)→ products is second order according to the expression -rA=kCACB and it is relatively slow compared to mass transfer so it takes place in the bulk of the liquid. Combine the following rate expressions for diffusion through the gas and liquid films‚ -rA=kAga(pA-pAi) and -rA=kAlaCAi-CA‚ with Henry’s law pAi=HACAi and the reaction rate

Summary This experiment will measure the rate of oxidation of iodide ions by persulphate ions to derive the rate law for the reaction. Starch will be added to the reaction to facilitate the measure of time during the reaction. The reactant solutions will contain (NH4)2SO4 and KI‚ represented as: (NH4)2S2O8 + 2KI -> I2 + (NH4)2SO4 + K2SO4 This can be simplified to: S2O82- + 2I- -> I2 + 2SO42- These equations can only be carried out and be visible after the iodine has completely
