Esterification (Alcohol & Carboxylic acid) - Reactions Mechanism & Uses with Videos

SOLVED:The ester of an organic base is hydrolyzed in a CSTR. The rate of this irreversible reaction is first-order in each reactant. The liquid volume in the vessel is 6500 L. A jacket with coolant at 18^∘ C maintains the reactant mixture at 30^∘ C . Additional data: Ester feed stream- 1 M, 30^∘ C, 20 L / s Base feed stream -4 M, 30^∘ C, 10 L / s Rate constant =10^14 (-11,000 / T) M^-1 s^-1, T in K ΔHr=-45 kcal / mol ester The average heat capacity is approximately constant
