# Problem:  The graph shown displays the effect of two different temperatures on the distribution of kinetic energies of molecules in a sample. One temperature is named "Lower T" and is graphed in blue. The other temperature is named "Higher T" and is graphed in red.If there was a third, new temperature that would be graphed in green and would display the effect of a greater, even higher temperature than "Higher T" on the distribution of kinetic energies of molecules in a sample, describe the shape and relative height of this new green curve as it relates to the existing red "Higher T" curve in the graph.

We’re being asked which gas has the largest molar mass at 25 ˚C.

In the graph, the y-axis is the fraction of molecules while the x-axis is the kinetic energy. According to the kinetic molecular theory of gases, the average kinetic energy of a gas is directly proportional to the temperature of the gas: a higher temperature results in a higher average kinetic energy.
