Answer:
Place the reactants in a smaller container.
Explanation:
If you were to reduce the source of heat, the hydrogen and oxygen molecules would lose their kinetic energy, resulting in less collisions.
_______________________________________________________
Maintaining the same temperature of the reactants, the speed would neither increase nor decrease as temperature is directly proportional to the kinetic energy of the molecules, which in turn is directly proportional to the number of collisions. However, placing the reactants in a smaller container would result in less volume, and hence the molecules would collide with one another more often!

Explanation:
Drawbacks of Dalton's Atomic Theory. The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects.
Answer:
Activation Energy
Explanation:
The main cause of slowness to start a reaction is the value of it activation energy. When metals possess low activation energy, it takes them time to start a reaction. But once started, the reaction becomes vigorous.
Activation Energy: the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.
