Consider the spontaneous dissolution of NaCl in
water NaCl(s) - Na (aq) + Cl(aq)
Predict whether the entropy change for this
process is positive or negative and explain your
answer.

Respuesta :

Answer:

Entropy is positive as liquids have greater disorder in terms of arrangement than that of solid ( use your entropy explanation for this) the Gibbs free energy change is positive as the reaction is spontaneous

Explanation:

Entropy is positive (use the entropy description) because liquids are more disordered in terms of placement than solids. Since the reaction is spontaneous, the change in Gibbs's free energy is positive.

What is entropy and how do you know if entropy change is positive or negative?

The entropy of an object is a measure of the amount of energy that is not available to do the job. Entropy is also a measure of the number of possible arrangements an atom can have in a system. In this sense, entropy is a measure of uncertainty or randomness.

Entropy increases as it changes from solid to liquid to gas. By examining the phase of the reactants and products, it is possible to predict whether the change in entropy is positive or negative. Entropy increases with each increase in gas mol
