The energy distribution profile (Curve C) for the Y2 molecules is shown in the graph below forthe reaction X+yz_XY2 when it is done under certain experimental conditions Line A represents the most probable energy of the Y2 molecules; and Line B represents the activation energy Which of the following changes should be made to the graph to explain the increase in the rata of the reaction if tho only change in experimental conditions Is tho addltion of a catalyst? Linc A Llne B 1 Curve C Moladul nr Fnomy haCurve C will broaden and Line B will move to the left; because have an energy greater than the minimum more Y2 molecules wlll energy barrier energy needed to overcome the activation ninimeB will move to the left because a larger fraction of minimum energy to overcome the activatiog the Y2 molecules will have the C Curve C and Line A will move to the energy barrier: molecules will Increase; right because the average energy of the Y2 Dilline ^ will move to the right because will increase the most probable energy of the Y2 molecules
