In an irreversible process taking place at constant `T` and `P` and in which only pressure-volume work is being done, the change in Gibbs free energy `(dG)` and the change in entropy `(dS)` satisfy the criteria

In an irreversible process taking place at constant T and P and in which only pressure- volume work is being done, the change on Gibb's free energy (dG) and changing in entropy (dS), stisfy the criteria

In an irreversible process taking place at constant P and T in which only pressure volume work is being done by the system the change in Gibb's energy (DeltaG) and change in entropy (Delta) , satisfy the criterion:

Products are favored in a chemical reaction taking place at a constant temperature and pressure. Consider the following statements : (i) The change in Gibbs energy for the reaction is negative. (ii) the total change in Gibbs energy for the reaction and the surroundings is negative. (iii) The change in entropy for the reaction is positive. (iv) The total change in entropy for the reaction and the surrounding is positive. The statments which are ALWAYS true are :
