# Problem: Find ΔS°rxn for the formation of Cu2O(s) from its elements.

###### FREE Expert Solution

In this problem, we are asked to determine ΔS°rxn for the reaction:

4 Cu(s) + O2(g) → 2 Cu2O(s)

To solve this problem, we use the following formula:

$\overline{){\mathbf{∆}}{{\mathbf{S}}}_{{\mathbf{rxn}}}{\mathbf{=}}{\mathbf{S}}{{\mathbf{°}}}_{{\mathbf{product}}}{\mathbf{-}}{\mathbf{S}}{{\mathbf{°}}}_{{\mathbf{reactant}}}}$
