$CO + \frac{1}{2}{O_2} \to C{O_2};\,\Delta H = Y$
Then the heat of formation of $CO$ is
On addition of equal number of moles of a non-volatile solute $S$ in equal amount (in $kg$ ) of these solvents, the elevation of boiling point of solvent $X$ is three times that of solvent $Y$. Solute $S$ is known to undergo dimerization in these solvents. If the degree of dimerization is $0.7$ in solvent $Y$, the degree of dimerization in solvent $X$ is. . . . . . .
