Question

6. Which of the following chemical reactions is most likely to have the largest equilibrium constant K?  
 
CH3COO- (aq) + H2O(l)  =  CH3COOH(aq) + OH-(aq)

HCl(aq) + H2O(l)  = H3O+(aq) + Cl-(aq)

CH3COOH(aq) + H2O(l) = CH3COO- (aq) + H3O+(aq)

H3PO4(aq) + NH3(aq) = H2PO4-(aq) + NH4+(aq)

B. HCl(aq) + H2O(l) = H3O+(aq) + Cl-(aq)

Kyleigh · Answer

I got D. Given that D is the largest reaction, I would predict it would have the largest K value.
