Which statement if false in regards to the effects of pressure on a rate of reaction?
an increase in pressure decreases the volume, which subsequently increases the concentration of react
a decreases in pressure increases the volume, which subsequently increases the concentration of react
a change in pressure only effects gases in chemical reactions
an increase in pressure shifts a reaction to the side with less total moles of gas

Pressure changes affect a reaction by influencing the concentration of reactants based on volume. The equilibrium shifts according to the number of gas moles present.

Explanation:

An increase in pressure decreases the volume, which subsequently increases the concentration of reactants.

A decrease in pressure increases the volume, which subsequently increases the concentration of reactants.

A change in pressure affects gases in chemical reactions, particularly in terms of shifting the equilibrium based on the number of moles of gas present on each side.

An increase in pressure shifts a reaction to the side with fewer total moles of gas.
