If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change to reestablish equilibrium. If a chemical reaction is at equilibrium and experiences a change in pressure, temperature, or concentration of products or reactants, the equilibrium shifts in the opposite direction to offset the change. This page covers changes to the position of equilibrium due to such changes and discusses briefly why catalysts have no effect on the equilibrium position.
For example, if the system is changed in a way that increases the concentration of one of the reacting species, it must favor the reaction in which that species is consumed. In other words, if there is an increase in products, the reaction quotient, Qc, is increased, making it greater than the equilibrium constant, Kc.
Answer:
the volume of the sound will quarter
Explanation:
As you move far away from the source, the loudness of sound decreases. This is because as the distance from the source increases, the area it covers also increases thereby spreading the energy over a great area leading to lesser loudness and intensity.
As a result of this, sound intensity follows an inverse square law:
I ∝ 1/d²; where I is the intensity and d is the distance from source.
Therefore If a speaker is moved from 2 feet away to 4 feet away (increment of 2 feet), the volume of the sound would quarter (1/2² = 1/4)
