Why are chemical equilibria called dynamic equilibria?
1 answer:
Answer:
Because molecules are moving so they change from reactants to products and vice versa.
Explanation:
Hello,
In this case, it is widely known that chemical equilibrium is related with such condition at which the rate of consumption of reactants and formation of products tends to zero so their concentrations remain the same over the time. For instance, if we consider the formation of hydrogen chloride at equilibrium:
We can also see that the reactants, hydrogen and chlorine are consumed to form hydrogen chloride and it also goes back to its reactants in a dynamic equilibrium (because they are constantly changing).
Best regards.

Answer:
22.48°C is the final temperature of the solution.
Explanation:
Heat of neutralization of reaction , when 1 mol of nitric acid reacts= ΔH= -56.2 kJ/mol= -56200 J/mol
Moles of nitric acid = n
Volume of nitric acid solution =
Molarity of the nitric acid = 0.600 M
Moles of barium hydroxide = n'
Volume of barium hydroxide solution =
Molarity of the barium hydroxide= 0.300 M
According to reaction, 2 mol of nitric acid reacts with 1 mol of barium hydroxide .Then 0.486 mol of nitric acid will react with :
barium hydroxide.
Heat release when 0.486 mol of nitric acid reacted = Q
= ΔH × 0.486 = -56200 J/mol × 0.486 mol=-27,313.2 J
Heat absorbed by the mixture after reaction = Q' = -Q = 27,313.2 J
Volume of the nitric solution = 0.81 L = 810 mL
Volume of the ferric nitrate solution = 0.81 L = 810 mL
Total volume of the solution = 810 mL + 810 mL = 1620 mL
Mass of the final solution = m
Density of water = density of the final solution = d = 1 g/mL
Initial temperature of the both solution were same =
Final temperature of the both solution will also be same after mixing=
Heat capacity of the mixture = c = 4.184 J/g°C
Change in temperature of the mixture = ΔT =
22.48°C is the final temperature of the solution.
