O The electron moved up to an energy level and has an energy of 10.92 x 10-18).
The electron moved up to an energy level and has an energy of 21.72 x 10-19

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)
