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!

The answer to this item is determined by using the proper conversion factors and the dimensional analysis. For the given units, meter and centimeters, the conversion from millimeters are as shown below,
1 m = 1000 mm
1 cm = 10 mm
Conversion of 5.3 mm³ to m³.
= (5.3 mm³)(1 m/1000 mm)³ = 5.3 x 10⁻⁹ m³
Conversion of 5.3 mm³ to cm³.
= (5.3 mm³)(1 cm/10 mm)³ = 5.3 x 10⁻³ cm³
The answer to this item is therefore letter B. 5.3 x 10⁻⁹ m³.
