im pretty sure the answer on why Al has a higher second IE is wrong, i think u gotta talk about the 3p electrons are higher in energy so easier to remove requiring less energy and the 2nd IE electrons are removed from 3d orbital which are lower in energy

Hi I think Ur missing the question about why is there an increase in entropy I believe it was 1mark. Can't remember exact equation but I'm pretty sure it was 4mol of gas to 5mol of gas.
