Document Summary
Change in some quantity related to reactants or products per some specific time interval. Quantity = molar concentration of products or reactants. Give some examples of slow and fast reaction rates. At a molecular level, a2 and b2 must collide with each other for reaction to occur. Large numbers of collisions occur per unit time, but only a small fraction of collisions result in a reaction. A short lived state before the atom forms in to a molecule, the middle step for two atoms to become a molecule which is also known as the transition state. Minimum amount of energy needed by reacting particles to form the activated complex. True or false: highly spontaneous reactions are very fast. False; there is no direct correlation between rate and spontaneity. At higher concentrations of reactants, ___ collisions occur and reaction rates ____ Because the surface area of the wool is greater per square inch than that of the nails.
