Given that AHºrn = - 386.2 kJ for the following, calculate the AHºf for Fe(CO)5 (g). Fe203 (s) + 13 CO (g) = 2 Fe(CO)5 (g) + 3 CO2 (g)

Ch4 and ph3 are both covalent since they are composed both of non-metals.    ch4 is non- polar because of  london forces and has a geometry of tetrahedral  ph3 , on the other hand, is umbrella shaped polar and has dipole-dipole intermolecular force (imf) . since ph3 is polar, it has a stronger imf   

The velocity would be 2
