**Chemical Reactions:**
(a) \[[IrCl_6]^{2-} + [Co(NH_3)_5(CN)]^{2+} \rightarrow [IrCl_6]^{3-} + [Co(NH_3)_5NC]^{2+}\]
(b) \[[Co(NH_3)_5(H_2O)]^{2+} + [Cr(H_2O)_6]^{2+} \rightarrow [Co(NH_3)_5(H_2O)]^{3+} + [Cr(H_2O)_6]^{2+}\]
(c) \[[*Cr(H_2O)_6]^{2+} + [W(CN)_8]^{4-} \rightarrow [Cr(H_2O)_5F]^{2+} + [W(CN)_8]^{3-}\]
**Explanation:**
- **Equation (a):** This reaction involves the exchange of ligands on cobalt and iridium complexes. The \([IrCl_6]^{2-}\) oxidizes to \([IrCl_6]^{3-}\), while the \([Co(NH_3)_5(CN)]^{2+}\) is reduced to \([Co(NH_3)_5NC]^{2+}\).
- **Equation (b):** Shows a redox reaction between cobalt and chromium complexes, where \([Co(NH_3)_5(H_2O)]^{2+}\) is oxidized to \([Co(NH_3)_5(H_2O)]^{3+}\), and \([Cr(H_2O)_6]^{2+}\) remains unchanged.
- **Equation (c):** Demonstrates a ligand exchange and redox reaction, where \([*Cr(H_2O)_6]^{2+}\) combines with \([W(CN)_8]^{4-}\) to form \([Cr(H_2O)_5F]^{2+}\) and \([W(CN)_8]^{3-}\).
Note: The asterisk (*) and arrow directions may indicate specific experimental conditions or mechanistic pathways in these reactions.
