(Answered) Problem consider the following reaction at 225k2cu2o s rarr

Academics

Problem: Consider the following reaction at 225K:

2Cu₂O (S) → 4 Cu (S) + O₂ (g)

In one of your laboratory experiments, you determine the equilibrium; you determine the equilibrium constant for this process, at 225, is 7.048E-72. You are given a table of data that indicates the standard heat of formation (ΔH^o_Form) of Cu₂O is -170 kJ/mol. Based on this information, what is the standard entropy change (ΔS^o_rxn) for this reaction at 225K?
