Consider the following chemical equation: 2 SO2(g) + O2(g) ⇌ 2 SO3(g)At equilibrium, the concentration of SO2 was found to be 0.10 M, the concentration of O2 was found to be 0.20 M, and the concentration of SO3 was found to be 0.30 M. What is the value of the equilibrium constant (Kc) for this reaction at the given temperature?

Calculate the change in entropy for the combustion of methane gas (CH4) at constant pressure and temperature of 298 K. The products of the reaction are carbon dioxide gas (CO2) and water vapor (H2O). The molar entropy of CH4, CO2 and H2O at 298 K are 186.3 J/K/mol, 213.7 J/K/mol, and 188.8 J/K/mol, respectively.

A chemistry student wants to study the adsorption behavior of a gas on a solid surface. The Langmuir adsorption isotherm experiment is conducted at temperature T. After analyzing the data, the student finds that the maximum adsorption capacity (at saturation) is q moles of the gas per unit area of the solid surface. The student also determines the value of the Langmuir constant K, which is proportional to the affinity of the gas for the surface. Now, the student needs to determine the fraction of the surface that is covered by the gas molecules at a certain pressure P below the saturation
