Relationship between k, T, and Ea Graph

[Omeed_Partovi_1L]

I'm a little confused on how to interpret the graph on p.75 out the course reader. How are there more fraction of molecules with high temperature if the peak is lower on the y-axis than the low temperature's peak, and what exactly do they mean when they say fraction of molecules.

The y-axis is the fraction of molecules, so if the peak of the high temperature curve is lower that means that there are less molecules at that certain level of kinetic energy. As the graph shows, the further right you go on the x-axis, the greater the kinetic energy.

I assume that fraction of molecules refers to a part of the sum of molecules. So as the fraction increases, more of the molecules of the entire sample are affected.
