7 of 3 Y Reaction 1 Reaction 2 -- . Reaction Coordinate In an experiment done at a low temperature, one hour after the reaction started, Y was produced but almost no Z was produced. At a much higher temperature, one hour after the reaction started, both Y and Z had been produced. Which of the following best explains why very little Z was produced at the lower temperature? A A smaller number of X molecules had enough energy to overcome the activation energy barrier for reaction 2, and very little Z was produced в The higher average kinetic energy of the X molecules at the lower temperature resulted in very little Z produced. The greater collision frequency between X molecules at the lower temperature resulted in very little Z produced. The intermolecular forces between X molecules were much weaker, and very little Z was produced.
