What is the Correct Relationship Between Chemical Reactions and Temperature

Question

What is the correct relationship between chemical reactions and temperature?
A)All chemical reactions are endothermic,and therefore require warmer temperatures.
B)Warmer temperatures provide the activation energy required to start chemical reactions.
C)Warmer temperatures allow more energy to be released during a chemical reaction.
D)Chemical reactions are not dependent on temperature at all.

Accepted Answer

Increasing temperature provides the activation energy required to initiate chemical reactions, making them happen faster. This is because it increases the energy of the molecules, causing them to collide with greater force and with a greater frequency, increasing the likelihood of successful collisions that lead to a reaction.
