2) (20 points) Sucrose is readily hydrolyzed to glucose and fructose in acidic solutions. The concentration of sucrose is monitored, and yields the following data: 0 14 39 60 80 110 140 170 210 Time (min) 0.316 0.300 0.274 0.256 0.238 0.211 0.190 0.170 0.146 Sucrose (mol/L) Determine the rate law for this hydrolysis reaction, and determine the appropriate rate constant with appropriate units. What references did you use to assist you in answering this problem?

We have to check two values rate constant at different time. I they appear same. Then we order with the help of rate constant. from the table given At, t20 sucrose (Ac)-0-315 M At it = 14 min sucrose (A_120-300 11 let for pst order ont log [16] [At get the desire conc of 2 cone of k, = 2-303 7 t ki = 2-303 Ki 20:00 37 min' 14 Smin log 0-314 0-300 for, it= 39 min conc . log 0-316 0.274 8468ose Carl-0.274 M ko - 2.303 >> Ky -0.0037 min 39 min Since, ki & kq are same. of means Hydrolys's g sucrose follows ist order kinetics so, Rate law : Rate = k [Clos M2001] Rate constant: K = 0.0037 min Hence using the given the given data, we can find rate and rate constant
