Some bacteria are resistant to the antibiotic penicillin because they produce penicillinase, an enzyme with a molecular weight of 3104 g/mol that converts penicillin into inactive molecules. Although the kinetics of enzyme-catalyzed reactions can be complex, at low concentrations this reaction can be described by a rate equation that is first order in the catalyst (penicillinase) and that also involves the concentration of penicillin. From the following data: 1.0 L of a solution containing 0.15 g ( 0.15106 g) of penicillinase, determine the order of the reaction with respect to penicillin and the value of the rate constant. [Penicillin] (M) Rate (mol/L/min) 2.0106 1.01010 3.0106 1.51010 4.0106 2.01010
UCI Chemistry researchers, Prof. F. Sherwood Rowland and Dr. Mario Molina werefirst to discovered in 1973 that chlorofluorocarbons (CFCs) were depleting the Earth’sozone layer when released into the atmosphere. Once they reach the stratosphere, Clis released from the CFCs molecules by interaction with UV light. Free Cl atoms areable to react with ozone in a catalytic cycle that converts O3into the more stable O2.It is estimated that a single Cl atom is able to react with∼100000 O3molecules.Although CFCs production was banned in 1996, there are still a substantial numberof motor vehicle air conditioners (MVACs) that use CFC-12 (CF2Cl2) as refrigerant.The average CFC-12 emission rate from operating MVACs has been estimated tobe 59.5 mg per hour per vehicle (Zhang et al.Environ. Sci. Technol. Lett.2017).How much chlorine, in kg, is added to the atmosphere in a year due to 100 millionMVACs using CFC-12 as refrigerant?

Consider the reaction Mn+ + ne- ⇌ M. If ΔG*c = ΔG* + (1-α)nFE and η = E – Eeq, prove that ic = io exp[-(1-α)nFηa)/RT)].
Some sulfuric acid is spilled on a lab bench. You can neutralizethe acid by sprinkling sodium bicarbonate on it and thenmopping up the resulting solution. The sodium bicarbonatereacts with sulfuric acid according to:2 NaHCO31s2 + H2SO41aq2¡Na2SO41aq2 +2 H2O1l2 + 2 CO21g2Sodium bicarbonate is added until the fizzing due to the formationof CO21g2 stops. If 27 mL of 6.0 M H2SO4 was spilled,what is the minimum mass of NaHCO3 that must be addedto the spill to neutralize the acid?

When ethanol (CH3CH2OH) burns in oxygen, carbon dioxide and water are formed. (i) Write the equation which describes this reaction. (ii) Using the data below, calculate the value for ∆Ho for the combustion of ethanol. Hof (CH3CH2OH(l)) = - 277.0 kJmol-1 Hof (CO2(g)) = - 393.7 kJmol-1Hof (H2O(l)) = - 285.9 kJmol-1
One of the many remarkable enzymes in the human bodyis carbonic anhydrase, which catalyzes the interconversionof carbon dioxide and water with bicarbonate ionand protons. If it were not for this enzyme, the body couldnot rid itself rapidly enough of the CO2 accumulated bycell metabolism. The enzyme catalyzes the dehydration(release to air) of up to 107 CO2 molecules per second.Which components of this description correspond to theterms enzyme, substrate, and turnover number?
A vehicle airbag system works by using a series of chemical reactions. When sensors in the system detect a collision, a heat source instantly causes the decomposition of sodium azide at 300oC. This first reaction produces sodium metal and nitrogen gas. The formation of the nitrogen gas inflates the airbag, but unfortunately, the other product, sodium metal, is extremely dangerous and highly reactive. The sodium metal must undergo an immediate secondary reaction to transform into a safer substance. That’s where potassium nitrate gets involved. In the secondary reaction, sodium metal reacts with the potassium nitrate to form potassium oxide, sodium oxide, and additional nitrogen gas. This secondary generation of nitrogen gas also fills the airbag. Excess gas from the secondary reaction gets vented from e airbag. Finally, in the third and fourth reactions, the sodium oxide and potassium oxide react with silicon dioxide separately to product harmless and stable silicate glasses sodium…
