A is the answer that ud be looking for in chemistry :)
The correct answer is c. Temperature is the average kinetic energy of a sample so if two samples have the same temperature they will also have the same average kinetic energy. I hope this helps. Let me know if anything is unclear.
Answer:
O B. It represents the time it takes for half of the material to decay to a
daughter element.
Answer: Option (b) is the correct answer.
Explanation:
As the given reaction is as follows.

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.
