Question

In an experiment, a student wants to increase the rate of a reaction that involves gases. Which change to the reactants would accomplish this? Increase the volume to decrease 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 concentratio

Answer 1

Answer:

Decrease the volume to increase pressure and to increase concentration

Explanation:

A gaseous reaction is affected by the volume of the reactants. To increase the rate of the forward reaction, we need to ensure that the volume of the reactants is manipulated in such a way that the forward reaction is favored.

Thus, when the volume of reactants is decreased, the pressure increases.This increase in pressure has the same effect as increase in concentration. Hence, the rate of forward reaction increases.
