Number 5 please and please show all work
Number 5 please and please show all work b. Fe(s)+S(s) FeS(s) c. 2 Fe(s)+3/2 O(g)- Fe,Os(s) d. HF( HF(g) ANSWER: c, since you are going from a reactant in a gas form product 5.. Calculate ?rG" for the following reaction: C(diamond) + O.(g)- CO-(g) given that AfG [CO (9))-394.4 kJ/mol and AfG TC(diamond)] +2.9 KJ/mol ANSWER: -397.3 kJ/mol Calculate the standard entropy change fo the following reaction: Cu(s)+ 1/2 O(g) Cuo(s) given that S°(Cu(s)] - 33.17 JIK mol, s TO2(g)] - 205.07 JIK mol, and S (CuO(s)] 42.59 J/K mo ANSWER:-93.12 J/K Given the following information, calculate ?rGo for the reaction below at Mg(s) + 1/2 02(g) MgO(s) ArH-601.24 kJ/mol-rxn and ArS108.36 JK
Explanation / Answer
C(diamond) + O2 (g) ----> CO2
delta G rxn=deltaGf(products) -deltaGf(reactants)
=(-394.4)-(0+2.9)
=- 397.3 kJ
