WebNov 9, 2024 · This relationship is so important that it has been rearranged into a new equation, Gibbs Free Energy (G). First, multiply everything by T, giving: TΔSreaction − ΔHreaction > 0 multiplying by negative 1 (-1) and rearranging (noting the sign of the inequality switches when you multiply by negative one). ΔH − TΔS < 0 This is the … WebSo delta H is equal to qp. Let's say we are performing a chemical reaction, an aqueous solution under constant atmospheric pressure. The reactants and products of that chemical reaction make up the system and everything else makes up the surroundings. When heat flows from the surroundings to the system, the system or the reaction absorbs heat ...
