I'm trying to determine which is the stronger/weaker acid/base,

CO₃^-2 + H₂O      HCO₃^- + OH^-

the arrow pointing left is longer than the arrow pointing right, showing I think that the reaction is stronger in one direction, but other than the arrow what makes HCO₃^- the stronger acid and OH^- the stronger base,
I really appreciate your help thanks

Have you thought about using pK_a values?
