What is the value for ∆Soreaction for the following reaction, given the standard entropy values? Cgraphite(s) + O2(g) CO2(g)
Substance | So(J/Mol*K)
C(graphite (s))| 6
O2(g) | 205
co2 (g) | 214

A) +425
B) -425
C) +3
D) -3
ps. if you can state why the other options are wrong that would be helpful

We know that the reaction equation is:
C(s) + O₂(g) → CO₂(g)

We may substitute the values of entropy and add a term of ΔS on the left hand side to represent the change in entropy. Thus:

6 + 205 + ΔS = 214
ΔS = 3 J/mol*K

The answer is C.
