Describe the three steps of solution formation. be sure to include the details regarding the dissolving of the substance
Elza [17]

The three steps involve;

Step 1: Separation/expansion of the solute particles

Step 2: Separation/expansion of the solvent particles

Step 3; Combining the solute and solvent particles


The first two steps are usually endothermic. Step 3, nonetheless, can be either exothermic or endothermic and is significant in determining whether the dissolving process will be endothermic or exothermic.

Submit Which of the following best describes the reaction? 2 H2S(g) + 3 O2(g) → 2 H2O(g) + 2 SO2(g) A) AS has a large negative v
mash [69]

Answer:  B) \Delta S^0 has a small negative value.

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from  an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

\Delta S is positive when randomness increases and \Delta S is negative when randomness decreases.

2H_2S(g)+3O_2(g)\rightarrow 2H_2O(g)+2SO_2(g)

As there are 5 moles of gaseous reactants and 4 moles of gaseous products, the gaseous molecules are decreasing on moving from reactants to products, thus randomness decreases and \Delta S is negative.      

Thus  \Delta S^0 has a small negative value.
