Which of the following is NOT important as a contributing factor to photochemical smog? stagnant air...
Please answer #3 and #4 only Photochemical Smog Photochemical smog is a type of air pollution produced when sunlight acts upon motor vehicle exhaust gases, such as nitrogen oxides (e.g., NO, NO:) to form harmful substances such as ozone (0). These substances participate in a reaction cycle that determines the concentration of pollutants at different times during the day. Ozone Formation: NO:(), is formed by chemical reactions involving N2(g) and O-() at the high temperatures inside internal combustion engines in...

EXPERIMENT 3. Kinetic Study: The lodine Clock Reaction Prelaboratory Questions Name Fiza Chandning Laboratory Section 0000000000000000000000000000000000000000000000000000000000000000000000000000000 1. Consider the following reaction: 2 NO(g) + 4 NO, (g) + O2(g) The initial concentration of N, O, was 0.84 mol/L, and 35 minutes after initiating the reaction, all of the N,Os has been consumed. a) Calculate the average rate of the reaction over this 35-minute time interval. b) Is it correct to assume that the rate law is Rate = k[NO]? based...
answer the questions Experiment 1084-04: lodine Clock Reaction Purpose Determine the rate law for an iodine clock reaction and study the influence of st on that reaction abruptly that it can be as startling as the sudden sound of an alarm clock, hence the clock reaction Background Information chemical equations can be written for chemical reactions, only some will proceed while others do not. Among the ones that do proceed some reactions occur as soon as reactants are mixed, while...
can you do the 6-12 number 8 is multiple choice 6. The initial rates listed in the table below were determined for the reaction CO(g) + NO2(g) + CO2(g) + NO(g) at varied concentration of the reactants, CO and NO2. Determine the rate law of this reaction. Experiment Initial [CO] (mol/L) Initial [NO] (mol/L) Initial rate (mol/Ls) 5.0x10+ 3.5x10 3.4x10-8 5.0x10+ 7.0x10- 6.8x10-8 1.5x10 3.5x10 1.02x10-7 7. The half-life of the reaction C&H:(8) ► 2CH.g) at constant temperature is independent...
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...
Which of the following graphs best represents of penicillin, if the reaction is second order with respect to penicillin? For the reaction X_2 + Y + Z rightarrow XY + XZ, it is found that doubling the concentration of X_2 doubled the reaction rate, tripling the concentration of Y triples the rate, and doubling the concentration of Z has no effect. What is the rate law for this reaction? What is the unit for the rate constant for this reaction?...
