An ideal gas is expanded from $$\left( {{p_1},{V_1},{T_1}} \right)$$ to $$\left( {{p_2},{V_2},{T_2}} \right)$$ under different conditions. The correct statement(s) among the following is (are)
A
The work done on the gas is maximum when it is compressed irreversibly from $$\left( {{p_2},{V_2}} \right)$$ to $$\left( {{p_1},{V_1}} \right)$$ against constant pressure $${p_1}$$
B
If the expansion is carried out freely, it is simultaneously both isothermal as well as adiabatic
C
The work done by the gas is less when it is expanded reversibly from $${V_1}$$ to $${V_2}$$ under adiabatic conditions as compared to that when expanded reverseibly from $${V_1}$$ to $${V_2}$$ under isothermal conditions
D
The change in internal energy of the gas is (i) zero, if it is expanded reversibly with $${T_1} = {T_2}$$ , and (ii) positive, if it is expanded reversibly under adiabatic conditions with $${T_1}\, \ne \,{T_2}$$

Addition of excess aqueous ammonia to a pink colored aqueous solution of $$MC{l_2},6{H_2}O\left( X \right)$$ and $$N{H_4}Cl$$ gives an octahedral complex $$Y$$ in the presence of air. In aqueous solution, complex $$Y$$ behaves as $$1:3$$ electrolyte. The reaction of $$X$$ with excess $$HCl$$ at room temperature results in the formation of a blue colored complex $$Z.$$ The calculated spin only magnetic moment of $$X$$ and $$Z$$ is $$3.87$$ $$B.M.,$$ whereas it is zero for complex $$Y.$$ Among the following options, which statement(s) is (are) correct?
A
Addition of silver nitrate to $$Y$$ gives only two equivalents of silver chloride
B
The hybridization of the central metal ion in $$Y$$ is $${d^2}s{p^3}$$
C
$$Z$$ is a tetrahedral complex
D
When $$X$$ and $$Z$$ are in equilibrium at $${0^ \circ }C,$$ the color of the solution is pink
