How many moles of oxygen react with 37.5 moles of sulfur
dioxide in the production of sulfur
trioxide gas?

1 L of O2 reacts with 2 L of SO2.

Explanation:

From the balanced equation, 1 mol of oxygen

reacts with 2 mol sulfur dioxide.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
