If 0.100 mol of CoCl₂ is placed in a 10.0 L flask, calculate the equilibrium concentrations of all species for the following reaction.
a) [CoCl₂] = 0.100 M, [CO₂+] = 0.200 M, [Cl-] = 0.300 M
b) [CoCl₂] = 0.050 M, [CO₂+] = 0.100 M, [Cl-] = 0.150 M
c) [CoCl₂] = 0.010 M, [CO₂+] = 0.020 M, [Cl-] = 0.030 M
d) None of these
