Why do the coefficients of an elementary step equal the reaction orders of its rate law, but those of an overall reaction do not? This is generally not true, the coefficients cannot be used for the reaction orders of its rate law for either type of reaction. An elementary step uses an average reaction rate calculation while the overall reaction uses an instantaneous rate calculation. Overall reactions are always in dynamic equilibrium while elementary steps are not. An elementary step is a single molecular event and occurs in one step, but the overall reaction is generally a series of elementary steps which are not necessarily proportional to the product of the overall reaction concentrations.

A50.0g sample of liquid water at 0.0 c ends up as ice at -20.0 c. how much energy is involved in this change?

Many bird species build nests in which they raise their offspring. one of these species is known as the magnolia warbler. breeding pairs of magnolia warblers build nests out of pieces of grass and twigs. the female warbler will then lay her eggs in the nest and sit on the eggs for a few weeks until they hatch. after the offspring have hatched, the female will continue to sit on the newborn chicks to keep them warm. both the male and the female bring food for the offspring to eat until the young are mature enough to find food on their own. which of these most likely describes why birds such as the magnolia warbler build nests in which to raise their offspring? a. nest building decreases the amount of energy used by the parent birds to raise their offspring to adulthood. b. nest building increases the probability that the offspring will survive and eventually produce offspring of their own. c. nest building decreases the amount of food that the offspring require the adult birds to provide. d. nest building increases the probability of the offspring being located by airborne predators.
