Which one of the following statements is true? O A catalyst alters the equilibrium constant of a reaction and is neither a product nor a reactant in the overall equation. In order for a reaction to occur, product and reactant molecules must collide with each other. The transition state is a short-lived, high energy state, intermediate between products and reactants. In reactions that are first order in one reactant and first order in another, the slow step always involves a...

To understand how elementary steps make up a mechanism and how the rate law for an elementary step can be determined. Very often, a reaction does not tell us the whole story. For instance, the reaction NO2(g)+CO(g)→NO(g)+CO2(g)NO2(g)+CO(g)→NO(g)+CO2(g) does not involve a collision between an NO2NO2 molecule and a COCO molecule. Based on experimental data at moderate temperatures, this reaction is thought to occur in the following two steps: NO2(g)+NO2(g)→NO3(g)+NO(g)NO2(g)+NO2(g)→NO3(g)+NO(g) NO3(g)+CO(g)→CO2(g)+NO2(g)NO3(g)+CO(g)→CO2(g)+NO2(g) Each individual step is called an elementary step. Together, these...

Which of the following statements is/are correct? 1) The term e-Ea/RT in the Arrhenius equation is the fraction of reactant molecules having energy less than the activation energy Ea. 2) As a general rule, the probability of correctly oriented collisions between reactant molecules will be low if the molecules are structurally simple, and high if the molecules are complex. 3) The concentration dependence of the rate for an elementary process in a reaction cannot be determined from the stoichiometric coefficients...

Which of the following statements is CORRECT? a. Relative to sole proprietorships, corporations generally face fewer regulations, and they also find it easier to raise capital. Stockholders should generally be happier than bondholders to have managers invest in risky projects with high potential returns as opposed to safe projects with lower expected returns. There is no good reason to expect a firm's stockholders and bondholders to react differently to the types of assets in which it C. invests. Bondholders should...
A three-step mechanism has been suggested for the formation of carbonyl chloride: Step 1: Cl2 ===> 2 Cl (fast equlibrium) Step 2: Cl + CO ===> COCl (fast equilibrium) Step 3: COCl + Cl2 ===> COCl2 + Cl (slow) What is the molecularit

ch 14 answer each of these.
answer all 3 please
HI HCI reactants Reaction intermediates are species that are formed in one step of a mechanism and consumed in another step. For example, can act as an intermediate in the following reaction: H2(g) + 2Cl(g) + 2HCl(g) + 12(g). You can often express the concentration of in terms of the concentrations of the of the overall reaction to be consistent with the experimentally observed rate law as the overall reaction...
