At what temperature, the velocity distribution function for the oxygen molecules will have maximum v — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Peak is most probable speed $u_{mp} = \sqrt{2RT/M} = 400$. $160000 = 2 \times 8 \times T / 0.032 \implies T = 320 \text{ K} = 47^\circ\text{C}$. Therefore, correct answer is B.
