WebNote that the speed of an individual gas particle is: \[v =\sqrt{v_x^2+ v_y^2 = v_z^2} \nonumber \] Three speed expressions can be derived from the Maxwell-Boltzmann distribution: the most probable speed, the … WebDec 17, 2024 · B. O_2 should be the correct answer for the reasoning given. Just as you stated, the gas with the lowest molar mass should have the highest speed, and O_2 has the lowest molar mass. This relationship is true since KE = 1/2mv^2, so if the temperature, also known as the average kinetic energy, is constant, mass is inversely related to velocity.
