Chemistry - Chemical Equilibrium Question with Solution | TestHub

Given the reaction between two gases represented by $A_2$ and $B_2$ to give the compound $AB(g)$. $$A_2(g)+B_2(g)\rightleftharpoons 2AB(g)$$ At equilibrium, the concentration of $A_2=3.0\times 10^{-3}\mathrm{M}$ of $B_2=4.2\times 10^{-3}\mathrm{M}$ of $AB=2.8\times 10^{-3}\mathrm{M}$ If the reaction takes place in a sealed vessel at $527^{\circ }\mathrm{C}$, then the value of $K_c$ will beNEET 2012 (Mains)
