Nobody is answering on the physics part, so I am going to post here. FAN and Medal.
A student performs a reaction twice. In the second trial, she raises the temperature by 20ºC and notices that the reaction takes place more quickly. She concludes that the reaction must be endothermic. Explain why the student is incorrect.

endothermic is calling for it to be necessary to have heat to work, but that's not the case. it can work without heat, it's just adding heat makes it faster.
