- ANSWER OF A:
Take data of "Introduccion a la termodinamica en ingenieria
quimica, J.M, Smith; H. Van Ness 7° Edition":
ΔGºfH2CO(g)=-10230J/mol ΔHºGCO2(g)=-394359
ΔHºGH2O(l)=-237129J/mol;
ΔGºfO2=0
Then:
: 
If 2,48 moles of H2CO react:
![ΔGo 621258 × 2.48 Δ = 1540719 ,84 Joules 1540 ,72K]](http://img.homeworklib.com/questions/3c79fef0-b2a4-11ea-844f-9748c9aa3164.png?x-oss-process=image/resize,w_560)
