where S is entropy, V is volume, p is pressure, T is temperature, R is the ideal gas constant, Vm is
molar volume, B2 and B; are virial coefficients that depend on temperature T. Suppose B3 = 0, B2 =
-15.8x100 m moll and dB2/dt = 0.25x10 mmol K-, evaluate this expression for 1 mole of
argon in 25 cm at 303.15 K.​

Explanation:

Potassium and Sodium are both metals on the periodic table. Both elements are found on the s-block of the table. Therefore, it is not possible for both of them to combine to form a compound.

For a compound to form two elements must combine in a definite order to given  single product.

The combination is facilitated by a loss, gain or sharing of electrons between two species. This leads to an attraction between the combining species.

Both Sodium and potassium would prefer to lose electrons and there is no reason for them to combine to form a compound.
