Consider the reaction
Ni(s) + 4CO(g) ! Ni(CO)4(g)
Assuming the gases are ideal, calculate the
work done on the system at a constant pres-
sure of 1 atm at 75C for the conversion of
1.00 mole of Ni to Ni(CO)4.
I would convert 4 mols CO to volume using PV = nRT and the conditions listed.
After conversion, the volume is 1/4 that (because mols is 1/4 the original).
Work = p*delta V. P is 1 atm.
The unit is L*atm. That should be converted to J. Multiply by 101.325 to do that. You will need to add the correct sign also.
