The explanation for the change in rate constant has to be given for the list of changes given. Concept Introduction: The rate of reaction is the quantity of formation of product or the quantity of reactant used per unit time. The rate of reaction doesn’t depend on the sum of amount of reaction mixture used. The raise in molar concentration of product of a reaction per unit time or decrease in molarity of reactant per unit time is called rate of reaction and is expressed in units of mol/(L .s) . The variation in concentration of reaction or product over a certain interval of time is called average reaction rate. The equation that relates the reaction rate to the reactants concentrations that is raised to various powers is called as rate law. Rate law can be determined by the slow step or otherwise called as rate-determining step. To explain the change in rate

A small artisanal cheesemaker is testing the acidity of their milk
before it coagulates. During fermentation, bacteria produce lactic
acid (K₁ = 1.4 x 104), a weak acid that helps to curdle the milk and
develop flavor. The cheesemaker has measured that the developing
mixture contains lactic acid at an initial concentration of 0.025 M.
Your task is to calculate the pH of this mixture and determine whether
it meets the required acidity for proper cheese development. To
achieve the best flavor, texture and reduce/control microbial growth,
the pH range needs to be between pH 4.6 and 5.0.

For simplicity, you can use the generic formula HA to represent the acid
You can assume lactic acid dissociation is in water as milk is mostly water.
Temperature is 25°C
1. Write the K, expression for the dissociation of lactic acid in the space provided. Do not forget to
include state symbols.…
