a change in which factor will affect the rate of reaction only when gases are involved?\n○ temperature\n○ pressure\n○ surface area\n○ concentration

a change in which factor will affect the rate of reaction only when gases are involved?\n○ temperature\n○ pressure\n○ surface area\n○ concentration

Answer

Brief Explanations:

Temperature affects reaction - rate in all states. Surface area and concentration affect reaction - rate in solids, liquids, and gases. Pressure specifically affects the rate of reaction only when gases are involved as it changes the volume and thus the concentration of gas molecules.

Answer:

B. pressure
