Can Volume Affect Reaction Rate for liquid solution

Question

Will decreasing the volume (size of container) affect the reaction rate for the following phase destination?

X (s) + YZ (aq) ---> XY (aq) + Z (g)

The reactants are solid and aq, changing the size of container can increase, decrease or no change on

reaction rate?

Answer 1

As container volume increases without adding more gas, reaction rates of gas-phase reactions decrease, as these gases will collide less frequently in a larger space. The vice versa happens if the container volume decreases without adding more gas: The reaction rates for the gas phase reactions increase since the molecules will be colliding more often.
