Kinetics 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. (c) Potato is made edible by cooking it…

At what point on a Potential Energy curve would you find the energy needed for an effective collision?

Which of the following is true?   Decreasing the activation energy decreases the reaction rate. Decreasing the activation energy increases the reaction rate. The activation energy of an exothermic reaction is negative. There is no relationship between activation energy and reaction rate.
