≪Propose a reaction mechanism using the criteria presented in the lesson‚ with the third step as the rate-determining step. Hypothetical reaction: A + 2B + 4C ---> 2D + E The rate law has been determined to be [B]^1[C]^2≫ I had prepared the material below before I received your criteria. As you know‚ each step in a reaction mechanism is an elementary step. Each step is characterized by its molecularity. A step could be unimolecular‚ as in A → B or A → B + C It could be bimolecular as in 2A → B +

The mechanisms involved in motor development involve some genetic components that determine the physical size of body parts at a given age‚ as well as aspects of muscle and bone strength. The main areas of the brain involved in motor skills are the frontal cortex‚ parietal cortex and basal ganglia. The dorsolateral frontal cortex is responsible for strategic processing. The parietal cortex is important in controlling perceptual-motor integration and the basal ganglia and supplementary motor cortex

Mechanism description of Electric Iron introduction: An electric iron is a small appliance‚a handheld piece of equipment with a flat‚ roughly triangular metal surface that‚ when heated‚ is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are stretched and the fabric maintains its new shape when cool. description: The electric

There are three main Anti-Clotting Mechanisms. 1. Non-Specific Mechanisms - Endothelial Factors a) Smoothness of Endothelial Lining prevents Platelet‚ adhesion and Extension of clot into the Blood Vessels. b) Negatively Charged Particles present over the lining of the endothelial repels the clotting factors ( Protein Anions ) i.e Prevents Clotting - Velocity of Circulation - If Decreased - Leads to clotting 2.
