In the system $\mathrm{AB}\left(\mathrm{s}\right)\rightleftharpoons \mathrm{A}\left(\mathrm{g}\right)+\mathrm{B}\left(\mathrm{g}\right)$ doubling the equilibrium concentration of A will cause the equilibrium concentration of B to

change to one-half its original value

remain constant

change to a new value which cannot be predicted

change to two times its original value
