Explain the equilibrium constant Kp = 7.81x10-2 for the following reaction in the gas phase at a given temperature T:H2O(g) + Cl2O(g) = 2 HOCl(g)
Compute the pressure (in atm) of H2O(g) at equilibrium in the reaction vessel at temperature T if the initial pressures of H2O(g) as well as Cl2O(g) are both equal to 2.8x10-1 atm.
A molecule can be polar or nonpolar depending upon the nature of the bonds and the shape of the molecule. For a molecule that has different outer atoms the molecular symmetry will decide the polarity.
