The figure below shows the energy diagram for a reaction in the presence of a catalyst and in the absence of a catalyst. As you can see, the catalyst has decreased the activation energy of the reaction, which means that more molecules are able to surmount it and react.
The Rocori High School shooting was a school shooting that occurred at Rocori High School on September 24, 2003 in Cold Spring, Minnesota, United States.[1] The shooter was identified as Rocori High freshman John Jason McLaughlin,[2] who shot and killed 15-year-old freshman Seth Bartell and 17-year-old senior Aaron Rollins.
