there are a few ways to increase the rate of a reaction. what is altered when the amount of a substance in a given volume is increased?\no temperature\no concentration\no surface area\no pressure
Answer
Brief Explanations:
Concentration is defined as the amount of substance per unit volume. When the amount of a substance in a given volume is increased, the concentration of the substance increases. Temperature is related to the average kinetic energy of particles, surface - area is about the exposed area of a substance, and pressure mainly affects gaseous reactions in terms of volume - change effects on concentration of gases.
Answer:
concentration
