Question

The rates of exchange of CO on cis square-planar Ir complexes have been observed for the following reaction at 298 K [IrX2(CO)2]- + 2 CO <=> [IrX2(CO)2]- + 2 CO (*C = 13C) The observed rate constants were: X | k (L/mol s) Cl | 1,080 Br | 12,700 I | 98,900 All three reactions have large negative values of entropy of activation, a. Is this reaction associative or dissociative? b. On the basis of the data, which halide ligand exerts the strongest trans effect?

          The rates of exchange of CO on cis square-planar Ir complexes have been observed for the following reaction at 298 K

[IrX2(CO)2]- + 2 *CO <=> [IrX2(*CO)2]- + 2 CO (*C = 13C)

The observed rate constants were:
X | k (L/mol s)
Cl | 1,080
Br | 12,700
I | 98,900

All three reactions have large negative values of entropy of activation,
a. Is this reaction associative or dissociative?
b. On the basis of the data, which halide ligand exerts the strongest trans effect?

Step 1

We are given the rate constants for the exchange of CO on cis square-planar Ir complexes at 298 K. The rate constants are: $k_1 = 1.05 \times 10^3 \, L/mol \cdot s$ $k_2 = 12.7 \times 10^3 \, L/mol \cdot s$ $k_3 = 98.9 \times 10^3 \, L/mol \cdot s$ Show more…
