Which of the substances below will have the greatest standard molar entropy? C4H10(g) C4H10(l) Xe(g) Which of the substances below will have the greatest standard molar entropy? C4H10(g) C4H10(l) Xe(g) C4H10(g), because it is a gas and as such has translational, rotational, and vibrational modes, allowing for greater energy dispersal C4H10(l), because it is a liquid, so the molecules are in close contact with one another, making the dispersal of energy more efficient Xe, because it has the greatest molar...
