According to the key, the right option is a.
Gibbs free energy, also known as free enthalpy, is a thermodynamic property that measures the maximum amount of work that can be extracted from a system at constant temperature and pressure.
The change in Gibbs free energy (ΔG) is directly related to the spontaneity of a process. If ΔG is negative, the process is spontaneous and can occur without any external input of energy. If ΔG is positive, the process is non-spontaneous and requires an input of energy to occur.
The equation for calculating Gibbs free energy is ΔG = ΔH - TΔS, where ΔH is the change in enthalpy, T is the temperature in Kelvin, and ΔS is the change in entropy.
The value of Gibbs free energy indicates whether a reaction or process is energetically favorable or not. A negative value indicates that the reaction or process is spontaneous, while a positive value indicates that it is non-spontaneous.
Gibbs free energy is used to determine the direction and spontaneity of chemical reactions. It can also be used to calculate the equilibrium constant for a reaction, which is a measure of the extent to which the reaction will proceed towards products.
