Explain why do the coefficients of an elementary step equal the reaction orders of its rate law, however those of an overall reaction do not?
a) Overall reactions are for all time in dynamic equilibrium while elementary steps are not.
b) This is usually not true the coefficients cannot be used for the reaction orders of its rate law for either type of reaction.
c) An elementary step utilizes an average reaction rate calculation while the overall reaction uses an instantaneous rate calculation.
d) An elementary step is a single molecular event as well as occurs in one step however the overall reaction is generally a series of elementary steps which are not necessarily proportional to the product of the overall reaction concentrations.
Which is the correct arrangement of types of radiation when ordered in decreasing energy per photon. a. Radio waves, microwave radiation, ultraviolet light, X-rays
A student dissolved 0.1319g of an unknown diprotic acid in 100mL of distilled water. The acid was then titrated with 0.1005M NaOH solution. The second equivalence point showed the sharpest change in pH, and so it was used to determine the molecula..
