- Which rate law is unimolecular?arrow_forwardObtain the rate law based on the kinetic study of the reaction.arrow_forwardKinetics Broadly speaking, the factors that influence chemical reaction rates may be summarised as follows.Chemical nature of reactants (e.g. is the chemical reaction thermodynamically “downhill” so that it can occur spontaneously at all?)Reactant Concentration (or pressure for a gas)Physical state of reactants (e.g. phase, or surface area of solids)Presence of catalystTemperature For each of the following observations, which one of the five factors is most important, and briefly explain how/why that is the case. (a) The ability to sustain aerobic exercise is limited by the amount of haemoglobin in the blood. (b) Non-starch polysaccharides are large complex carbohydrates, and an important source of dietary fibre. Their chemical energy content is similar to other carbohydrates like sucrose. These molecules do not undergo respiration via by human digestion, but some bacteria have specialised proteins that can process non-starch polysaccharides.

- During polymerization, the system usually becomes more ordered as monomers link together. Could an endothermic polymerization reaction ever occur spontaneously? Explain.arrow_forwardPyrolysis involves heating compounds to break them into smaller molecules, and typically involves free-radical chain reactions. Pyrolysis of crude oil fractions is a common method of making smaller hydrocarbons from large-chain hydrocarbons. Pyrolysis of ethane, C2H6, forms ethylene and hydrogen gases C2H4 and H2 as the primary products. Suggest a mechanism for this pyrolysis reaction, labeling your reactions as initiation, propagation, and termination steps.arrow_forwardSubject name: Physical chemistry Q.2 Show graphically what is the effect of temperature on rate of biological, normal and explosive reactions.arrow_forward
