Question

Using the data in the table, determine the rate constant of the reaction and select the appropriate units. Trial (A) (M) 0.330 0.330 3 0.660 B (M) 0.380 0.760 0.380 Rate (M/s) 0.0215 0.0215 0.0860 A + 2B - CD Units

Answer 1

[A] [B] Rate 0.0215 0.330 0,330 0,660 0,380 0,760 0.380 0.0215 0.0860 * from eq♡ and 2 Rate [B] is changed but reaction is not changed. So, depants on CB ] . Rate = k [A]an (B)" rate of Rate is not here n=0 # from eq and & ③ As the [A] is double then - 4 time of its value i Rate = K[Agn [B7% Reute become = - =CAJI m=2 Rate = K[A2²CB2° Rate = K[A²

- isec, * from eq o CA] = 0; 330 Rate = 0.0215 nike Rate =kCAR 0.0215 = k (0,330)2 k = 0.0215 (0.8330)? K = 0.1974 mat, st
