The correct 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 enzymes have an optimal temperature range where they function most effectively. As temperature increases, the kinetic energy of molecules increases, leading to more frequent collisions and thus a higher reaction rate. However, if the temperature exceeds the optimal range, enzymes can denature, losing their functional shape and thereby decreasing the reaction rate.
