Determine the net force acting on the object. Then, write whether or not there will be a change in motion. If yes, write the direction the object will move in.

Calculate the change in entropy if br2(l) is converted to br2(g). s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)
