The equilibrium constant at 298 K for the reaction $\mathrm{A}+\mathrm{B} \rightleftharpoons \mathrm{C}+\mathrm{D}$ is 100 . If the initial concentrations of all the four species were 1 M each, then equilibrium concentration of D (in $\mathrm{mol} \mathrm{L}^{-1}$ ) will be
Among the following 0.1 m aqueous solutions, which one will exhibit the lowest boiling point elevation, assuming complete ionization of the compound in solution?
Variation of solubility with temperature t for a gas in liquid is shown by the following graphs. The correct representation is




180 g of glucose, $\mathrm{C}_6 \mathrm{H}_{12} \mathrm{O}_6$, is dissolved in 1 kg of water in a vessel. The temperature at which water boils at 1.013 bar is _________ (given, $\mathrm{K}_{\mathrm{b}}$ for water is $052 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$. Boiling point for pure water is 373.15 K )
