Document Summary

Increasing temperature should increase rate: using the collision theory of chemical kinetics, explain your prediction in question 1. Molecules must collide to react so higher temperature means faster molecules and therefore more collisions. Open the phet simulation reactions & rates (google it or https://phet. colorado. edu/en/simulation/legacy/reactions-and-rates: first click on the two green plus buttons in the separation view and energy view windows. Note that the flat blue line on the left of the energy view window represents the energy of the reactants and the line at the right the products. Pull the plunger back to fire a yellow a atom at the. Bc molecule with the total energy (green line on the right) at the following levels. Briefly describe what happens (hit reload launcher between each trial: total energy between the reactant and product energies. Molecules collide but no reaction: total energy above the product energy but below the maximum energy peak on the blue curve.
