Interpretation Introduction
Interpretation:
The equilibrium constant Kp value should be derived given the oxygen removal reaction.
Concept Information:
Thermodynamics is the branch of science that relates heat and energy in a system. The four laws of thermodynamics explain the fundamental quantities such as temperature, energy and randomness in a system. Entropy is the measure of randomness in a system. For a spontaneous process there is always a positive change in entropy. Free energy (Gibbs free energy) is the term that is used to explain the total energy content in a thermodynamic system that can be converted into work. The free energy is represented by the letter G. All spontaneous process is associated with the decrease of free energy in the system. The equation given below will enable us find the spontaneity of a reaction. The equation given below helps us to calculate the change in free energy in a system.
ΔG = ΔΗ- TΔS
Where,
ΔG is the change in free energy of the system
ΔΗ is the change in enthalpy of the system
T is the absolute value of the temperature
ΔS is the change in entropy in the system
Equilibrium constant: The state in which the reactants and products have no net change over time. This is when the forward and reverse reactions occur at equal rates, this state of equilibrium can be described by the equilibrium constant (K).
Free energy (Gibbs free energy) is the term that is used to explain the total energy content in a thermodynamic system that can be converted into work. The free energy is represented by the letter G. All spontaneous process is associated with the decrease of free energy in the system. The standard free energy change (ΔG°rxn) is the difference in free energy of the reactants and products in their standard state.
