List at least four experimentally determined parameters that you, an experimenter, can define when exploring the hydrolysis of ethyl benzoate by aqueous sodium hydroxide.
The aqueous-phase decarboxylation of CH2NO2CO2H, CH2NO2CO2H CH3NO2(aq) + CO2(g), is studied at a certain temperature, giving the following data: Time (s) [CH2NO2CO2H] (M) 0.0e+00 0.100 1.0e-01 0.0466 2.0e-01 0.0217 3.0e-01 0.0101 4.0e-01 0.00473 Figure out whether this reaction is first-order or second-order with respect to the concentration of CH2NO2CO2H. Calculate the value of the rate constant. Pick the choice from below which gives the correct reaction order and value of the rate constant for this reaction.
The iodide-catalyzed decomposition of hydrogen peroxide is thought to proceed by a four-step mechanism: H2O2(aq) + I-(aq) --> HOI(aq) + OH-(aq) (slow)HOI(aq) + OH-(aq) --> H2O(l) + OI-(aq)OI-(aq) + H2O2(aq) --> HOOI(aq) + OH-(aq)HOOI(aq) + OH-(aq) --> H2O(l) + O2(g) + I-(aq) (a) If the first step of this mechanism is rate-determining (slow), choose the correct rate law for the overall process. Rate = k [HOI] [H2O2] Rate = k [H2O2]2 Rate = k [I-] [H2O2] Rate = k [H2O2]2 [H2O2] Rate = k [I-] [HOI] Rate = k [H2O2] [H2O2] (b) Choose the correct chemical equation for the overall process. HOI(aq) + OH-(aq) --> H2O(l) + OI-(aq) H2O2(aq) + I-(aq) --> HOI(aq) + OH-(aq) 2 H2O2(aq) --> 2 H2O(l) + O2(g) (c) Identify an intermediate in the reaction.

The first-order rate constant, k1, for the decomposition of ampicillin at pH 5.8 and 35?C is k1 = 2 × 10-7 sec-1. The solubility of ampicillin is 1.1 g/100 mL. If it is desired to prepare a suspension of the drug containing 2.5 g/100 mL, calculate the zero-order rate constant, k0, and the shelf-life, that is, the time in days required for the drug to decompose to 90% of its original concentration (at 35?C) in solution. Note: 100 mL = 1 deciliter = 1 dL.
In a chemical reaction with activation energy E. = 20 kJ/mol, (a) how many folds the rate constant is increased when the temperature increases from 300 K to 1000 K? That is, the ratio of k(1000K)/k(300K). (b) In the presence of a catalyst, the activation energy is brought down to 10 kJ/mol, how many folds the rate constant is increased at the same temperature 300K?
Below is a proposed mechanism for ClO–(aq) reacting with I–(aq) in the presence of OH–(aq). ClO- +H2O --> HOCl +OH- (fast, reversible)I- +HOCl --> HOI +Cl- (slow)HOI + HO- --> IO- +H2O You are trying to show that the rate law for this proposed mechanism matches an experimentallydetermined one. What is the expression for koverall or k’ for the proposed mechanism?Note: When writing an expression, H2O is not involved (just don’t include it).
