Which of the following gases will have the slowest rate of effusion at constant temperature? A)H₂ B)F₂ C)Ne D)SO₃ E)CF₄

Question

Quizplus · Accepted Answer

The rate of effusion of a gas is inversely proportional to the square root of its molar mass (Graham's law). Among the given options, CF4 (with the chemical formula correctly interpreted from the given notation as CF₄) has the highest molar mass, thus it will have the slowest rate of effusion.
