methyl acetate is to be hydrolyzed by water in a batch reactor at constant temperature. The forward rate constant with some hydrogen ions as a catalyst is 0.000148 liter/mol*min, and the equilibrium constant is 0.219. The initial concentration of ester is 1.51 mol/lit and of water is 48.76 mol/lit. Find: A) the equilibrium concentration of ester b) the time required for 90% of this equilibrium yield to be obtained c) the final composition of the reactor charge assuming no volume change
