The reaction is associated with a decrease in the number of particles in the same phase (3 mol→2 mol), so overall, a decrease in entropy: ΔS ⦵ for the reaction is negative. Hence, applying ΔG ⦵ = ΔH ⦵ ⦵, ΔG ⦵ will be negative (ΔG ⦵ <0), and the reaction spontaneous, if ΔH ⦵ >TΔS ⦵.

Is the reaction endo the rmic or ...1 answer · Top answer: a) exo the rmic; b) 25 kJ The diagram below represents a spontaneous reaction (deltaG degree < 0). Exergonic reactions are also called spontaneous reactions, because they can occur without the addition of energy. Reactions with a positive ∆ G (∆ G > 0), on the other hand, require an input of energy and are called endergonic reactions. In this case, the products, or final state, have more free energy than the reactants, or initial state. The image represents a spontaneous, gaseous reaction at a constant temperature T K.

Entropy is a mathematically defined property in thermodynamics. It can often help to understand it as a measure of the possible arrangements of the atoms, ions, or molecules in a substance. The symbol for entropy is S, and a change in entropy is shown as "delta" S or ΔS. If the entropy of a system increases, ΔS is positive.
