The study of reaction rates is called ___________. kinetics reaction rate refers to how quickly or slowly the ____ disappear and the _____ appear reactants, products if a reaction is to occur, reacting particles must first _______ and this ________ must be effective collide, collision what are two characteristics of an effective collision sufficient energy (lower activation energy) and correct orientation five major factors that affect reaction rate temp, concent...

reaction rate The change in concentration of a reactant or product per unit time collision theory atoms, ions, and molecules can react to form products when they collide, provided that the particles have enough kinetic energy Factors that affect reaction rate nature of the reactants, concentration, pressure of gases, temperature, surface area and the presence of a catalyst Nature of the reactants small molecules with fewer bonds, ionic bonds, single bonds will react fast...

Reaction Rate time it takes for the reactant to become the product; no chemical reaction is instantaneous For minimum energy required for chemical reaction to occur: must separate (work is done); particles are broken down by dipolar water molecules; ions must fight throught the water to re-combine 3 ways used to study reaction rate: (1) Measure the time it takes for the product to first appear;(colorless to a color) (2) Measure the time it takes for one or both reactants to b...

Three Domains Archea, Bacteria, Eukarya Hierarchy Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species Zone of inhibition The clear region around the paper disc saturated with an antimicrobial agent on the agar surface. The clear region is an indication of the absence, or the effective inhibition, of microbial growth by the antimicrobial agent. Koch's Postulates 1. The suspected causative agent must be found in every case of the disease and be absent from he...

prevalence number of existing cases / number of population incidence number of new cases / number of persons at risk of developing disease relationship between incidence and prevalence prevalence = incidenceXduration relationship between incidence rate and mortality rate mortality rate easier to obtain than incidence - use when case-fatality rate is high - use when duration of disease is short importance of surveillance - monitor changes in disease frequency -...
