The rate constant of a particular ester hydrolysis reaction was determined by examining the presence of its products in multiple trials. The average rate constant was found to be. K c = .3275g Introduction Compounds in liquid and gas states are constantly undergoing change. The state at which they stop reacting and remain at constant molar ratios is called equilibrium. The reaction studied in this experiment is the hydrolysis, reaction with water, of and unknown ester compound. ester + H 2 O alcohol + acid The   symbol in the chemical equation denotes that the reaction is constantly going  back in forth. To express the ratio of products vs reactant at equilibrium we find the rate  constant.  K c. =products/reactants Methods Four different bottles with different concentrations of reactants were prepared and left to sit and reach equilibrium for a week. To find the equilibrium concentrations of products,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
