The carbon dioxide in the headspace above the liquid is at higher pressure than atmospheric pressure outside the can.
The gas is at a lower volume initially but suddenly has a larger volume available when the can is opened.
The change in pressure as the gas rapidly moves to become dispersed through its new volume causes the "whoosh" sound.
The gas law that applies is Boyle's law.
This above is the exact answer for edgunity
Answer: (D) concentration of the products remains constant.
Explanation:
The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.
For a chemical equilibrium reaction, equilibrium state is achieved when the rate of forward reaction becomes equals to rate of the backward reaction.Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.
Thus at chemical equilibrium, the amount of product and reactant remains constant because the rates of the forward and reverse reactions are equal.
A chemical equilibrium is dynamic in nature forward and backward reactions continue for indefinite time and never stops.
During evaporation, liquid particles on the surface momentarily gain enough energy due to random thermal motion to overcome the intermolecular attractions and escape into the gas phase. These evaporating particles, by virtue of gaining energy, also increase in velocity.
Thus, the correct answer here would be the third choice.
