Question

The following data were obtained on the initial rates of reaction of a d-metal complex in aqueous solution.

For the experiments a.  [Y] = 2.7 mmol/dm3,

and for experiments b. [Y] = 6.1 mmol/dm3

Conc. complex/(mmol dm-3) 8.01 9.22 12.11
Exp. a.  v/ (mol dm-3 s-1) 125 144 190
Exp. b.   v/ (mol dm-3 s-1) 640 730 960

 

(a) What is the order of reaction with respect to the complex AND the reactant Y. Choose one.

(b) use the data above to calculate the rate constant.

k = ________  (mol/L/s,  s-1,  L/mol/s, or L2/mol2/s). 3 s.f. normal format.
