If the Equilibrium Constant for the Reaction A $\leftrightarrow$ B Is 05, and the Initial Concentration of a Is 30 MM

If the equilibrium constant for the reaction A $\leftrightarrow$ B is 0.5, and the initial concentration of A is 30 mM and of B is 15 mM, then the reaction

A) will proceed in the direction it is written, producing a net increase in the concentration of B.
B) will produce energy, which can be used to drive ATP synthesis.
C) will proceed in the reverse direction, producing a net increase in the concentration of A.
D) is at equilibrium.
