After setting up the following spontaneous reaction in a beaker,

CaCO₃(s) + 2 HCl(aq) ⟶ CaCl₂(aq) + H₂O(l) + CO₂(g),

you notice that the temperature of the solution increases. Which statement best describes the process:

Group of answer choices

Not enough information is provided.

ΔS_surr > 0

ΔS_surr < 0

ΔS_sys < 0

ΔS_univ < 0

Solutions

Expert Solution

Answer is ∆Ssurr >0

Here, ∆n >0

And the process is exothermic.

So, ∆Ssys > 0

And ∆Ssurr > 0

And ∆Suniv = ( ∆Ssys + ∆Ssurr ) > 0
