(a) Select all of the correct statements about reaction rates from the choices below. The lower the rate of a reaction the longer it takes to reach completion. The rate of a slow step has more effect on the overall reaction rate than the rate of a fast step. The fastest step in a reaction is called the rate-determining step. The rate of a fast step has more effect on the overall reaction rate than the rate of a slow step. Reactions involving very unstable combinations of chemicals have small rate constants. Reaction rate constants increase with increasing temperature. The slowest step in a reaction is called the rate-determining step.

A reaction mechanism is defined as the sequence of reaction steps that define the pathway from reactants to products. Each step in a mechanism is an elementary reaction, which describes a single molecular event of usually one or two molecules interacting. The rate law for an overall reaction is the rate law for the slowest step in the mechanism, which is directly related to the stoichiometric coefficients of the reactants. The exception to this rule occurs when the slowest step...

Identify correct statements pertaining to reaction energies. Group of answer choices The rate of a reaction depends on the energy change between reactants and products. If Keq < 1, the equilibrium will favor the reactants. If ∆G° < 0, Keq will be greater than 1. The reaction step with the highest energy transition state is called the rate determining step.

(a) Select all of the correct statements about the relative acid strengths of pairs of acids from the choices below. O HCl is a stronger acid than H2S because Cl is more electronegative than S. OH3PO4 is a stronger acid than H3AsO4 because P is more electronegative than As. HBrO4 is a stronger acid than H2SO4 because Br is more electronegative than Se. HPO42- is a stronger acid than H3PO4 because it has more charge (is more unstable). H2Se is...
