... Vapor pressure depression is relatively easy to understand on the basis of a physical model. At the surface of a liquid there is a competition between the kinetic energy of the molecules (thermal energy), which is trying to push the molecules off the surface into the gas phase, and the intermolecula ...

Template for calculating the ΔH° in a multiple step chemical reaction
... To make Al2O3, you need the O3 from Fe2O3. To do that, you must first carry out the process of breaking up the Fe2O3, which has its own enthalpy of formation. However we are not forming Fe2O3. We are decomposing it. So, we must reverse the equation. Fe2O3 → 2Fe(s) + 3/2 O2 (g) Since the equation is ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
