#19 Choose the nght statement about residence time in a reactor I. The residence time in CSTR and PER are proportional to the total flowrate of solution. II. Conversion increases with the time the spent by the reactants in the reactor. III. Residence time is defined as the as the reactor volume divided by the total feed flow rates. #16 Which statement is true about enzyme activity? | The amount of glucose produced per ml in the reaction mature per unit time. 11. Temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators are the factors affecting enzyme activity II. The rate of an enzyme catalysed reaction increases as the temperature is raised IV Extremely high or law pH values generally result in complete loss of activity for most enzymes Answer O II and III II, III and IV
