Consider the following 5 plots of concentration ?? versus position ?? across a barrier (indicated by the orange highlighting). All 5 plots are on the same scale. Assuming that the barriers all have the same area ?? and same diffusion coefficient ??, rank the (magnitude of the) rate at which molecules cross the barriers, from largest to smallest.

Learning Goal: To understand the ideal gas law and be able to apply it to a wide variety of situations. The absolute temperature T, volume V, and pressure p of a gas sample are related by the ideal gas law, which states that pV nRT. Here is the number of moles in the gas sample and R is a gas constant that applies to all gases. This empirical law describes gases well only if they are sufficiently dilute and at a sufficiently high temperature that they are not on the verge of condensing. In applying the ideal gas law, p must be the absolute pressure, measured with respect to vacuum and not with respect to atmospheric pressure, and T must be the absolute temperature, measured in kelvins (that is, with respect to absolute zero, defined throughout this tutorial as -273°C). If p is in pascals and Vis in cubic meters, use R 8.3145 J/(mol-K). If p is in atmospheres and V is in liters, use R = 0.08206 L-atm/(mol-K) instead.

A gas thermometer registers an absolute pressure of 305 mm of mercury when in contact with water at the triple point. What pressure does it read when in contact with water at the normal boiling point?

How can the equation of the diffusion coefficient be expressed in terms of the Boltzmann constant now in terms of R and N (gas constant and number of Avogadro, respectively).
