3.2 - The hydrolysis of ethyl ester of acetic acid (ethyl acetate) inan aqueous solution is first-order reaction (catalyzed by H3O+ions).a) Write the equation for this reaction. It is a bimolecularreaction. Explain why it is not a second order reaction.Under what conditions should the hydrolysis of acetateEthyl be a reaction of the second order?b) As the total acidity of the reaction mixture increases duringthe reaction, the process ofhydrolysis can be monitored by titration with a measuredsodium hydroxide solution. Forsolving the kinetic quation we use the relation (picture below)where VO is the volume of the measured NaOH solutionrequired for the titration of H+ ionsat time t = 0, Vt is the volume of NaOH solution correspondingto the titration at time t and Voo isthe volume of the NaOH solution corresponding to the time t =co (after the reaction is completed)We put 200cm3 of HCl solution with a concentration of 1 mol dm-3 into the Erlenmeyer flask using measuringcylinder.A measuring cylinder is placed in a 250 cm3 Erlenmeyer flask,200 cm3of HCI solution with a concentration of 1 mol dm-3. The flask is immersed in the thermostatset to the selected temperature. After tempering the contents, it is added to the bank10 cm3 of ethyl acetic acid (from the bottle on which its molarity is indicatedM = 88.11 g mol-1, weight 901 g and volume 1000 ml), the mixture is brieflyshook and we immediately take 5 cm3 of the sample into cooled water with a dry pipettein the titration flask (and the Erlenmeyer flask is returned to the thermostat). It is necessary to have a titrationflask with 50 cm3 of cooled distilled water readyat a temperature of 0 to 5 °C.Why is the titration sample prepared in this way (poured into cool water)?СОАCAV₂-V₁VoV-V

Given a reaction between an organic molecule, denoted as A, and NaSH, we observe the following observations. Using the observations, write a rate law for the reaction.(a) The rate triples when the concentration of [A] is tripled and the concentration of [NaSH] is held constant.(b) The rate is decreased when the concentration of [A] is doubled and the concentration of [NaSH] is cut by a factor of 3.(c) The rate doubles when the concentration of [A] is cut in half and the concentration of [NaSH] is quadrupled.(d) The rate increases with an increase in temperature. write the rate law
The reaction of the alkene, ethylene, with H2 produces ethane as a product. However, the reaction is incredibly slow in the absence of a catalyst, such as platinum metal. What is the role of the catalyst in speeding up the reaction? Raising the activation energy by breaking the bonds of hydrogen molecules. By bringing together the hydrogen atoms and alkene on the same metal surface, thereby lowering the activation energy. By decreasing the number of reactive inermediates. By increasing the equilibrium constant for the reaction.

In the second paragraph you should explain why 2-chloro-2-methylpropane reacts with water via the SN1 mechanism instead of the SN2 mechanism, and then write the steps in the mechanism for this reaction. Then write the balanced equation for the reaction between 2-methyl-2-chloropropane and water. One of the products of this reaction is HCl. The rate at which HCl is produced is equal to the rate at which 2-chloro-2-methylpropane is consumed. In this experiment, the HCI will be neutralized by incremental addition of a sodium hydroxide solution. Write the balanced equation for the reaction between NaOH and HCI.
