(N/A) The Maxwell-Boltzmann distribution curve shows how the fraction of molecules varies with kinetic energy at different temperatures. As the temperature increases,the curve shifts and changes shape as follows:   Lower Temperature $(T)$ Higher Temperature $(T + 10)$   $(i)$ The curve is narrower. $(a)$ The curve is broader.   $(ii)$ The peak (maximum fraction of molecules) is higher. $(b)$ The peak (maximum fraction of molecules) is lower.   $(iii)$ The peak shifts towards the left (lower kinetic energy). $(c)$ The peak shifts towards the right (higher kinetic energy).   $(iv)$ $A$ smaller fraction of molecules possesses energy greater than the activation energy $(E_a)$. $(d)$ $A$ larger fraction of molecules possesses energy greater than the activation energy $(E_a)$.

How does the graph of the fraction of molecules versus kinetic energy change at different temperatures?
