A student ran the following reaction in the laboratory at 581 K: COCl2(g) CO(g) + Cl2(g) When he introduced COCl2(g) at a pressure of 0.872 atm into a 1.00 L evacuated container, he found the equilibrium partial pressure of Cl2(g) to be 0.390 atm. Calculate the equilibrium constant, Kp, he obtained for this reaction. Kp =

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?
