Give detailed Solution with explanation needed
W ↑ To determine the spontaneity of a chemical reaction, the sign of AG rather than the sign of AS is generally used. This is because O (1) AG is always positive and AS may be positive or negative O (2) Free energy free and it is easier to understand than entropy. O (3) AG is always larger than AS O (4) none given #3 3 A Moving to the next question prevents changes to this answer.
