    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

    Polymerization reaCTIONS polymers are high-molecular-weight compounds‚ fashioned by the aggregation of many smaller molecules called monomers. Ex. plastics that have so changed society and the natural and synthetic fibers used in clothing are polymers. Classification of polymers Homopolymers - consist of repeated long chains or structures of the same monomer unit. Ex. PVC(polyvinyl chloride) Copolymers - polymers that consist of more than one molecule. Trimers - molecules consisting

    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

    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

    Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY  AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation
