HELP Read the following reactions.

Reaction 1: NaCl(s) → Na+(aq) + Cl−
Reaction 2: CaCO3(s) → CaO(s) + CO2(g)

Which reaction leads to an increase in entropy? (4 points)
Only Reaction 1
Only Reaction 2
Both Reaction 1 and 2
Neither Reaction 1 nor 2

The correct answer is: Only Reaction 1.

Explanation:

Ok, allow us to define what entropy is: entropy could be a measure of the random activity in an exceedingly system, and there are several factors which may affect the number of entropy during a system - as an example after you increase temperature, you increase entropy.

In this case,

Reaction 1: NaCl(s) → Na+(aq)+Cl- (aq): during this reaction you're solvating the atoms of Na+ and Cl-, or in other words, you're passing a compound from the solid state to the liquid state, which causes the entropy to extend. Liquids have more energy and entropy than solids.

Reaction 2: N2(g) + 3H2(g) → 2NH3(g): during this case you're getting a gaseous product from gaseous reactants, and although there's positive entropy, it doesn't increase.

[A] Only Reaction 1.

EXPLANATION:

We know that Entropy also increases when solid reactants form liquid products. Entropy increases when a substance is broken up into multiple parts. The process of dissolving increases entropy because the solute particles become separated from one another when a solution is formed. Entropy increases as temperature increases.

So, Correct choice - [A] Only Reaction 1.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
