Question
1) Write Kc expression for the following reaction: Co^(3+)(aq) + 6NH_3 (aq) <-----> (Co(NH_3)_6)^(3+) (aq)2)Using the following initial concentrations measured, [Co^(3+)]=3.0x10^(-4)M , [NH_3]=2.0M , [Co(NH_3)_6^3+)]=0.0M . The value of Kc for this reaction is 4.0x10^10. Determine the equilibrium concentrations for all species in the reaction.
3)using the equilibrium concentration of (Co(NH_3)_6)^(3+) calculated assume a path length of 1cm, calculate the molar absorptivity of this complex ion, the measured absorbance is 0.85.
help with any 3 would be wounderful!
pls help! need last 3 questions by tomarrow morning. will give high rating!
