7. The decomposition of ammonium chloride to form ammonia and hydrogen chloride occurs NH,Cl→ NH3(e + HCle AH = 176 kJ according to the following reaction: a) Predict the sign of the entropy change, AS, for this reaction. Justify your answer. b) The value of AG° for the reaction is negative at high temperatures but positive at low temperatures. Explain.
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.
