Answer: Option (b) is the correct answer.

Explanation:

As the given reaction is as follows.

$2H_{2} + O_{2} \rightarrow 2H_{2}O$

So, when we decrease the temperature for this reaction then there will be decrease in kinetic energy of reactant molecules. As a result, less number of collisions will take place.

Hence, there will be decrease in rate of chemical reaction.

Thus, we can conclude that in the given reaction decreasing the temperature would also decrease the rate of reaction.
