Best Answer: Atomic oxygen is just one oxygen atom by itself, written as O. Molecular oxygen is a molecule of two oxygen atoms covalently bonded together, such that both atoms attain the stable octet configuration. It is written as O2. The molar mass simply means the mass of a substance in one mole (in grams). You can refer to your periodic table for the mass number. In this case, oxygen has a mass number of 16.0. Hence, atomic oxygen has a molar mass of 16.0g while molecular oxygen has a molar mass of 16.0*2 = 32.0g.
A reaction's equilibrium constant, Keq, measures the extent to which reactants are converted to products by the reaction. reaction's equilibrium constant, Keq, measures the extent to which reactants are converted to products by the reaction.
Equilibrium, Chemical. the state of a system in which one or more reversible chemical reactions occur and in which the forward and reverse rates for each reaction are equal. The composition of the system therefore remains constant so long as the conditions of its existence are preserved.hemical equilibrium. (chemistry). A condition in which a chemical reaction is occurring at equal rates in its forward and reverse directions, so that the concentrations of the reacting substances do not change with time. Also known as equilibrium.
