Ответ:
Reason:
According to Le Chatelier's principle: "If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change and a new equilibrium is established."
So, more reactant (weak acid or weak base) would result in shift of equilibrium towards right (i.e. toward products). Hence, the conc. of products would increase so that new equilibrium could be established.

V₂ = 15.27 L
Explanation:
Given data:
Initial volume = 14.0 L
Initial temperature = 25°C (25 + 273.15 = 298.15 k)
Final temperature = 52°C = (52+273.15 = 325.15 k)
Final volume = ?
Solution:
Charles Law:
" The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure "
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 14.0 L × 325.15 K / 298.15 k
V₂ = 4552.1 L.K / 298.15 K
V₂ = 15.27 L
