Question

why does reaction with oxygen requires initial heating
​

Answer 1

Answer:

If heating is required in order to get a reaction happening within an observable time frame, this means that the activation energy required is significant for the reaction, and that you must supply a certain amount of energy in order to push the molecules towards the threshold of beginning the reaction.
