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 esteris 1.51mol/lit and of water is 48.76mol/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
