Here is my explanation about the reaction between hydrogen or methane and oxygen.
Hydrogen molecules and oxygen molecules can collide sucessfully and react if they have enough energy. In room temperature, molecules are moving slowly, but they do have a chance to collide, and they do have a chance to have high energy level to collide successfully. Therefore, even in room temperature, hydrogen can slowly react with oxygen to form carbondioxide and water.
And as temperature increases, the chance to collide and to have enough energy gets bigger, so rate of reaction increases.
PS: the kenetic energy of particles satisfies something like normal distribution, so molecules with high energy must exist even in low temperature.
My chemistry teacher don't agree with me. why?
Which brought me to a second question: what is the definition of ignition point(the minimal temperature required to burn) if reaction can happen just at any temperature?
