\(a\) and \(y\) respectively are

If '\(a\)' stands for the edge length of the cubic systems. The ratio of radii in simple cubic, body centred cubic and face centred cubic unit cells is

A metal crystallises in a body centred cubic lattice with the metallic radius \(\sqrt3\mathop A\limits^o\). The volume of the unit cell in \(\mathrm{m}^3\) is

In solid state, \(\mathrm{PCl}_5\) is a/an

Aqueous solution of raw sugar when passed over beds of animal charcoal, it becomes colourless. Pick the correct set of terminologies that can be used for the above example.

For Freundlich adsorption isotherm, a graph of \(\log (x / m)\) vs \(\log (p)\) gives a straight line. The slope of line and its \(Y\)-axis intercept respectively are

A gas at a pressure of \(2 \mathrm{~atm}\) is heated from \(25^{\circ} \mathrm{C}\) to \(323^{\circ} \mathrm{C}\) and simultaneously compressed of \(\frac{2}{3}\)rd of its original value. Then the final pressure is

Lattice enthalpy for \(\mathrm{NaCl}\) is \(+788 \mathrm{~kJ} \mathrm{~mol}^{-1}\) and \(\Delta H_{\text {hyd }}^{\circ}=-784 \mathrm{~kJ} \mathrm{~mol}^{-1}\). Enthalpy of solution of \(\mathrm{NaCl}\) is

Temperature of \(25^{\circ} \mathrm{C}\) in Fahrenheit and Kelvin scale respectively are
