Answer 1

The most accurate response is:

The rate of a chemical reaction initially increases with increasing temperature and then decreases, eventually stopping, when the temperature gets too high.

This is because, typically, as temperature rises, the kinetic energy of molecules increases, leading to more frequent collisions and a higher rate of reaction. However, if the temperature exceeds a certain threshold, it can denature enzymes, causing a decrease in activity and eventually halting the reaction.
