A rightward change in equilibrium.
The concentration of gases = [H2] will decrease, [N2] will increase, [NH3] will increase when the new equilibrium is reached.
Additional heat is produced.
The forward and backward reactions' rates quicken in the new equilibrium.
The equilibrium constant decreases as more heat is released.
the exothermic nature of the process.
The equilibrium constant would not have changed if the temperature had remained constant.

The symbol %v/v means percent by volume. Assuming there is no volume effects when these substances are mixed, we calculate as follows:
% v/v = (25 mL ethanol / 25 mL + 150 mL ) x 100
%v/v = 14.29 mL ethanol / mL solution
Hope this answers the question.
Answer:
Ionic bond
Explanation:
When Na loses an electron, it becomes positive ion.
When Cl gains an electron, it becomes negative ion.
The electrostatic attraction between these ions is an ionic bond.
