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

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 always decreases with increasing temperature and always increases with decreasing temperature.
The rate of a chemical reaction always decreases with increasing temperature and always increases with decreasing temperature.

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.

Enzyme activity typically increases with rising temperatures up to an optimal point, where the enzyme is most active. Beyond this optimal temperature, the enzyme can denature, leading to a decrease in activity.
