In the reaction below, what does the symbol "⇌" mean?
OH⁻(aq) + NH₄⁺(aq) ⇌ H₂O(l) + NH₃(g)
A. The reaction is reversible
B. The reaction is balanced.
C. The rate of forward and reverse reactions are the same.
D. All the species present will appear in the expression for the equilibrium constant.
E. The forward reaction does not progress.
F. The backward reaction happens as fast as the forward reaction and so the proton is not transferred at all.
G. No net changes in concentrations are occuring.
H. The reaction is not balanced.
I. If we knew the concentrations of the species, we could determine an equilibrium constant value and the extent of the reaction.
J. The reaction cannot decide which way to go.
