In a​ race, 37 out of the 50 cyclists finished in less than 37 minutes. What percent of cyclists finished the race in less than 37 ​minutes? Write an equivalent fraction to find the percent.

I believe the correct answer would be last option. The reaction is categorized as an endothermic process since it absorbs heat. This type of reaction requires a supply of heat energy in order for the reaction to proceed. Without the heat energy, the activation energy would not be reached and no reaction can be seen.
