The number of collisions of Ar atoms with the walls of container per unit time — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

the wall collision rate of a specific gas species (ar) per unit area depends only on its own number density (n/v) and its average speed c_avg (which is constant at constant temperature). adding another gas (co2) at constant volume and temperature does not alter either of these parameters for ar, so its wall collision rate remains unchanged.
