2. The investigation of the reaction represented by the equation: X (g) + Y (g) → Z (g), allowed to establish that the reactive cross-section in this reaction at 25.0 °C was 7.50 x 10-21 m². This was possible when comparing the experimental Arrhenius factor with the one predicted using collision theory. It is also known that the collision cross- sections of X and Y, estimated from their transport properties, are 0.95 nm² and 0.65 nm², respectively. a) If the masses are 15.5 amu and 21.7 amu for X and Y, respectively, and the rate constant is 5.25 mM-1 s-1, determine the activation energy of this reaction. b) If the steric factor in this reaction is assumed to be 1, by how much would the reaction rate increase?

List at least four experimentally determined parameters that you, an experimenter, can define when exploring the hydrolysis of ethyl benzoate by aqueous sodium hydroxide.
Substances that poison a catalyst pose a major concern for many engineering designs, including those for catalytic converters. One design option is to add materials that react with potential poisons before they reach the catalyst. Among the commonly encountered catalyst poisons are silicon and phosphorus, which typically form phosphate or silicate ions in the oxidizing environment of an engine. Group 2 elements are added to the catalyst to react with these contaminants before they reach the working portion of the catalytic converter. If estimates show that a catalytic converter will be exposed to 625 g of silicon during its lifetime, what mass of beryllium would need to be included in the design?

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
