Lab: Types of Reactions

Question 12 • IA-Chemistry A Survey of Chemistry A

What would you expect to happen if you raised the temperature of the water to 85°C? Check all that apply.

Answer
A
The reaction rate would be faster than the rate at 65°C.
B
The reaction rate would be slower than the rate at 0°C.
C
The reaction rate would be equal to the rate at 65°C.
D
The reaction rate would be slower than the rate at 95°C.

Explanation

As water temperature increases, particles move faster and collide more often with enough energy to react, so the reaction rate generally increases. At 85°C, the reaction would be faster than at 65°C, making A correct. It would also be slower than at 95°C, making D correct; it would not be slower than at 0°C or equal to the rate at 65°C.
