Chemistry - Chemical Equilibrium Question with Solution | TestHub

An equilibrium mixture in a vessel of capacity$\mathrm{100\; litre}$contain$\text{1}\text{mol}$${\mathrm{N}}_2,$$2\text{mol}$${\mathrm{O}}_2$and$\text{3}\text{mol}\text{NO}$. Find number of moles of${\mathrm{O}}_2$to be added, so that at new equilibrium the concentration of$\text{NO}$is$\text{0}\text{.04}\text{mol/lit}\text{.}$.
