1. Consider the reaction described by the equation Cr(H2O)63+ (aq) + SCN- (aq) → Cr(H2O)5SCN2+ (aq) + H2O(1)

For which the following initial-rate data were obtained at 25°C:

[Cr(H2O)63]0 (M)

[SCN-]0 (M)

Initial rate (M/s)

1.0x10-4

0.10

2.0x10-11

1.0x10-3

0.10

2.0x10-10

1.5x10-3

0.20

6.0x10-10

1.5x10-3

0.40

1.2x10-9

(a) Determine the rate law and the value of the rate constant for the reaction.

 

(b) If the rate constant at 50°C is found to be 2x10-5 M-1 s-1, what is the activation energy of this reaction?

 

(c) If a catalyst were used, what do you expect to happen with the activation energy?
