Increase the volume to dec ease pressure and to increase concentration.
Increase the volume to increase pressure and to decrease concentration.
Decrease the volume to decrease pressure and to increase concentration
Decrease the volume to increase pressure and to increase concentration.
O
O

Answer 1

D. Decrease the volume to increase pressure and to increase concentration.

Step-by-step explanation:

I took the test on edge 2020 and got it right, hope this helps:)

Answer 2

Decrease the volume to increase pressure and to increase concentration.

Step-by-step explanation:

Increasing the concentration will increase the number of collisions per second and therefore the rate of reaction.

A and B are wrong. You want to decrease the volume.

C is wrong. According to Boyle's Law, you can't decrease both the volume and the pressure at the same time.
