urease Consider the enzymatic reaction: Urea 2NH3 + CO If 5 g/L urease is added, the rate of reaction is given as a function of urea concentration in the table below: Cura mol/L 0.2 - mol/L-s 1.08 0.02 0.01 0.005 0.002 0.55 0.38 0.2 0.09 In 0.5L batch reactor, the initial concentration of urea is 0.1 mol/L, and urease concentration is 0.1 g/L (1) Calculate the time needed to convert 99% of the urea (2) If a competitive inhibitor with a concentration of 0.03 mol/L and K, = 0.005 mol/L, calculate the time needed to reach 99% conversion
