By definition, Bronsted-Lowry acid is a proton donor in the acid-base neutralization reaction. When a weak acid like acetylsalicylic acid is reacted with water, the water here acts as the Bronsted-Lowry base. This is possible because water has properties of amphoterism - can act as an acid or base. In this case, acetylsalicylic acid would have to donate its H+ atom to water, so that it would yield a hydronium ion, H₃O⁺. The complete net ionic reaction is shown in the picture.
So, in the reaction, the products yield are the acetylsalicylate ion and the hydronium ion.

Answer:
Pressure will decrease according to the Charles Gay Lussac law.
Explanation:
When there is a gas in a tank, and the moles of gas are not modified, neither the volume, we can notice that pressure will be modifying, in order to the absolute temperature, as directly proportion.
T° increase → Pressure increase
T° decrease → Pressure decrease
If the pressure keeps on constant, it will be the volume that would be modified according to the absolute T°, as a directly proportion.
Volume increase → T° increase
Volume decrease → T° decrease
Let's go to the maths
P₁ / T₁ = P₂/T₂
100 kPa / 333K = P₂ / 283K
(100 kPa / 333K) . 283K = P₂ → 84.9 atm
As T° has decreased, pressure also decreased.
Answer:
Decrease the volume to increase pressure and to increase concentration
Explanation:
A gaseous reaction is affected by the volume of the reactants. To increase the rate of the forward reaction, we need to ensure that the volume of the reactants is manipulated in such a way that the forward reaction is favored.
Thus, when the volume of reactants is decreased, the pressure increases.This increase in pressure has the same effect as increase in concentration. Hence, the rate of forward reaction increases.
