Consider the Reaction a + B ⇌ 2 AB

Consider the reaction A + B ⇌ 2 AB.The vessel on the right contains an equilibrium mixture of A atoms (shaded spheres) ,B atoms (unshaded spheres) ,and AB molecules.
-If the barrier between the two vessels is removed and the contents of the two vessels are allowed to mix,what will be observed?

A) The reaction will go in the forward direction decreasing the number of A atoms and B atoms and increasing the number of AB molecules.
B) The reaction will go in the forward direction increasing the number of A atoms and B atoms and decreasing the number of AB molecules.
C) The reaction will go in the reverse direction decreasing the number of A atoms and B atoms and increasing the number of AB molecules.
D) The reaction will go in the reverse direction increasing the number of A atoms and B atoms and decreasing the number of AB molecules.
