Example: 1) N2 ,75 K ) Nola look) the nitrogen atoms are more dispersed in the gaseous Phase: Entropy will increase 2) Co, la 57 C) ta cos Is. -80 C) o as temperature decreases the molecules slow down to a more ordered, less chaotic state, Entropy will decrease More atorns per molecule and higher molecular mass give rise to higher entropy. Standard Entropy change equationi As yn = En sop products - E s (reactants) S Standard molar en tropy n and m = reaction coefficientsExample HCl(a) + Nad NaOH(s) -- Nads the Asprm =[kielle (po la -[1 mol) [186.9 km) + line = -109,2 J/k Gibbs energy of formation valves is tound using Gibbs energy of reaction equation A Guryn E. GO (products)- GP (reactants) Spontaneous reactions have a negative value for the Gibbs energy chang . $ Enthalpy or entropy alone does not deter reaction spontaneity, but one can identify the signs of AHans As thet contribute favorably to spontaneity.
