Question

There are a few ways to increase the rate of a reaction. When the amount of a substance in a given volume is increased, this is altering the

Answer 1

2.concentration

Step-by-step explanation:

The cup with hot water has the faster reaction. The particles in hot water have more energy, so they move faster and collide with each other more often.

1.temperature

2.concentration

3.surface area

4.pressure

have a good da hope this helps

Answer 2

If the volume remains the same, but the amount (number of moles) is increased, this is an increase in concentration, which is defined as amount per volume (usually moles/liter).
For some reactions, increasing the concentrations also causes the rate of reaction to increase.
