"Transition metal elements" are the type of element which have atomic radii which remain relatively constant across a period.
Periods refer to the horizontal lines of the periodic table. Each period represents the sequential occupation of an atom's valence shell orbitals, also with longer periods representing the employment of an atom's d subshell orbitals.
As the atomic number rises, more electrons, as well as protons, are present, increasing attraction over time, which drives the atomic radius to shrink over time.
Therefore, "Transition metal elements" are the type of element which have atomic radii which remain relatively constant across a period.

The equilibrium constant of the reaction is 0.323.
Equilibrium constant:
It is expressed as the ratio of concentration of the products to the concentration of reactants. It is represented by K.
The relationship of K with G (Gibbs free energy) is expressed as:
G° = -RTlnK
Here R is the gas constant, T is the temperature.
Calculations:
Convert 25°C to K.
25°C = (25 + 273.15) K
= 298.15 K
Substitute the values in the above expression.
2.8 x 1000 J/mol = -8.314 J/mol.K x 298.15 K x ln(K)
lnK = 2800 J/mol/(-8.314 J/mol.K x 298.15 K)
lnK = -1.13
K = e^-1.13
= 0.323

Answer:
If you're trying to memorize something, I'd suggest you'd look over the piece multiple times, and if that doesn't help maybe turn it into a little song that you can remember.
Explanation:
Personally I find making a little song easier to remember, and if that doesn't help, just make sure you keep trying, and maybe even do a little bit of digging on Google to find more things such as songs that have already been made to memorize the piece.
