Consider the decomposition of a metal oxide to its elements, where M represents a generic metal. M203(s)---> 2M(s) + 3/2 O2(g) info given for Gf(kJ/mol): M203= -10.60 M(s)=0 O2(g)= 0 1.) what is the standard change in Gibbs energy for rxn as written in forward direction? (k...

My answer is: deltaS(sys)=654900J/mol*K deltaS(surr)=466.4 J/mol*K deltaS(univ)=655366J/mol*K Sorry I forgot to convert to J also I checked this problem and I only got thedeltaS(surr)=466.4 J/mol*K correct. Please help
chemistry
DrBob222 could you please answer!!!!!!
chemistry
Also I don't know how you are working this problem out.
chemistry
So what are the answers for deltaS(sys)=? J/mol*K deltaS(surr)=? J/mol*K deltaS(univ)=? J/mol*K I need to verify the correct answers. Could you please tell me...Thanks!
