Question 1 • Chemistry

The production of water proceeds according equation. 2 cap h sub 2 g plus cap o sub 2 times g rightarrow 2 cap h sub 2 cap o g Which describes a way to speed up the collisions between hydrogen and oxygen molecules to produce more water?

Answer
A
Place the reactants in a smaller container.
B
Reduce the concentration of the reactants.
C
Use a less-intense source of heat on the reactants.
D
Maintain the same temperature of the reactants.

Explanation

Placing the reactants in a smaller container gives the hydrogen and oxygen molecules less space to move around in. They are therefore closer together and collide more often, which can speed up the reaction and produce water faster. Reducing concentration would make collisions less frequent, while keeping the temperature the same or using less heat would not increase collision frequency.
