Propionic acid in an aqueous solution is produced according to the reaction: C2H5COONa + HCL CH3COOH + NaCl In a laboratory test, equimolar quantities of sodium propionate (MW = 96 g/g-mol) and hydrochloric acid (MW = 36.5 g/9-mol) were added into a laboratory scale batch reactor so that the concentration was 2.7 g-mol per liter for each reagent. Sampling was made over predetermined time intervals and the following data was gathered: 30 Time, min Conversion of Sodium Propionate, % 0 0 10 39 20 55 50 72.5 64 80 It is known that the reaction is second order and reversible. Determine the rate constants of the forward and backward reactions, as well as the equilibrium constant
