Question

Which describes a way to speed up the collisions between hydrogen and oxygen molecules to produce more water?
a Use a less-intense source of heat on the reactants.
b Maintain the same temperature of the reactants.
c Place the reactants in a smaller container.
d Reduce the concentration of the reactants.

Answer 1

One way to speed up a chemical reaction is to increase the kinetic energy of the reactant molecules. Will any of these choices result in increased kinetic energy (aka temperature)?

Answer 2

c) By placing the reactants in a smaller volume, the distance between the molecules decrease which allows for more successful collision to take place(water molecules forming at a higher rate).
