Question
1. The rate of the hydrolysis of sucrose to glucose is quite slow in the absence of a catalyst. Sucrose + water glucose + fructose a. If the initial concentration of sucrose is 0.050M, it takes 440 years for the initial concentration of the sucrose to decrease by half to 0.025M. What is the rate of disappearance, (M-s-1) of sucrose in the absence of a catalyst? b. If a catalyst is present, the hydrolysis of sucrose is much more rapid. If the initial concentration of sucrose is 0.050M, it takes 6.9 x 10-5 s for the concentration of sucrose to decrease by half to 0.025M. What is the rate of the disappearance of sucrose in the presence of a catalyst? c. Determine the velocity of the uncatalyzed reaction when the concentration of sucrose is 0.050M. The rate law is: rate = k [sucrose]. The rate constant for the uncatalyzed reaction is 5.0 x 10-11 s-1. d. Determine the velocity of the catalyzed reaction when the concentration of sucrose is 0.050M. The rate law is: rate = k [sucrose]. The rate constant for the catalyzed reaction is 1.0 x 10^4 e. The enzyme catalyzed reaction has a KM of 0.135 mM and a Vmax of 65?Mlmin. What is the reaction velocity when the concentration of sucrose is 1.0 mM?
