Slightly to the right of the peak. $$v_avg = \sqrt\frac8RT\pi M$$ Use this to find the mean of the molecular speeds.
Here are some extension questions related to the Maxwell-Boltzmann distribution: Slightly to the right of the peak
The high-energy tail is very sensitive to temperature; even a small ( \Delta T ) causes a large increase in the fraction of molecules with ( E > E_a ). Slightly to the right of the peak
Remember that the distribution never actually touches the x-axis; there is always a non-zero probability of finding an incredibly fast molecule. Slightly to the right of the peak
