How does temperature affect enzyme activity in a chemical reaction?(1 point)

Responses

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 then decreases, eventually stopping, when the temperature gets too high.

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

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 increasing temperature and continues to increase indefinitely as temperature continues to increase.

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 statement accurately reflects the general trend observed in enzyme activity and many chemical reactions, where increasing temperature typically enhances reaction rates up to an optimal point, after which the enzyme may denature and the reaction rate decreases.
