The enzyme urease enhances the rate of urea hydrolysis at pH 8.0 and 20oC by a factor of 1014. If a given quantity of urease can completely hydrolyze a given quantity of urea in 5.0 min at 20oC and pH 8.0, how long would it take for this amount of urea to be hydrolyzed under the same conditions in the absence of urease?
