Determine the value of the equilibrium constant, kgoal, for the reaction n2(g)+h2o(g)⇌no(g)+12n2h4(g), kgoal=? by making use of the following information:
1. n2(g)+o2(g)⇌2no(g), k1 = 4.10×10^−31
2. n2(g)+2h2(g)⇌n2h4(g), k2 = 7.40×10^−26
3. 2h2o(g)⇌2h2(g)+o2(g), k3 = 1.06×10^−10

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?
