The volume of a colloidal particle, $V_C$ as compared to the volume of a solute particle in a true solution $V_S$, could be:

The solubility product of a salt having general formula ${\text{MX}}_2$, in water is $4\times 10^{-12}$. The concentration of ${\text{M}}^{2+}$ ions in the aqueous solution of the salt is:

Benzene and toluene form nearly ideal solutions. At $20^{\circ }\text{C}$, the vapour pressure of benzene is $75\text{torr}$ and that of toluene is $22\text{torr}$. The partial vapour pressure of benzene at $20^{\circ }\text{C}$ for a solution containing $78\text{g}$ of benzene and $46\text{g}$ of toluene in torr is:

The exothermic formation of ${\text{ClF}}_3$ is represented by the equation:
$${\text{Cl}}_2(g)+3{\text{F}}_2(g)\rightleftharpoons 2{\text{ClF}}_3(g);{\Delta }_{r}H=-329\text{kJ}$$
Which of the following will increase the quantity of ${\text{ClF}}_3$ in an equilibrium mixture?
