The rate of a chemical reaction initially increases with increasing temperature and continues to increase indefinitely as temperature continues to increase.
The rate of a chemical reaction initially increases with increasing temperature and continues to increase indefinitely as temperature continues to increase.

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

Answer 1

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 reflects the enzyme activity behavior, where increasing temperature generally boosts reaction rates up to an optimal point, beyond which the enzymes may denature and lose their functional structure, leading to a decrease in reaction rate.
