I've seen a lot of incorrect approaches to this problem. Can you please make sure it is correct? 1.3377 seems to be an accurate value for x in part a). Please make sure the x value makes sense when solving for it with the equilibrium constant. Thank you!

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 0.000148liter/molmin, 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
