(a) Give the chemical name of Ir(CO)CI(PPh 3 ) 2 (either of the two isomers). (b) Sketch all isomers of the octahedral complex Cr(H2O), FBrCl (hint: there are five, and two of the five are enantiomers of each other).

In acidic aqueous solution, the purple complex ion Co(NH3)5Br2+ undergoes a slow reaction in which the bromide ion is replaced by a water molecule, yielding the pinkish-orange complex ion : Co(NH3)5(H2O)3+ Co(NH3)5Br2+Purple(aq)+H2O(l) → Co(NH3)5(H2O)3+Pinkish−orange(aq)+Br−(aq)The reaction is first order in Co(NH3)5Br2+, the rate constant at 25 ∘C is 6.3×10−6 s−1, and the initial concentration of Co(NH3)5Br2+ is 0.100 MM. What is its molarity after a reaction time of 19.0 h ? How many hours are required for 85 %% of the Co(NH3)5Br2+ to react?
