3.2.4 Which curve X or Y represents experiment 1? Use collision theory to explain the answer.
(Note: The curves X and Y are not provided in the image, but typically in Maxwell-Boltzmann distribution graphs, one curve represents a lower temperature (more peaked, shifted left) and the other a higher temperature (flatter, shifted right). Assuming Experiment 1 is at a lower temperature than Experiment 2, and X represents the lower temperature curve.)

Curve X represents Experiment 1.
According to collision theory, at a lower temperature (Experiment 1), the average kinetic energy of the reactant particles is lower. This means that a smaller fraction of particles will possess kinetic energy equal to or greater than the activation
