Consider the reaction where `K_(p) = 0*497 "at 500 K`` PCl_(5) (g) hArr PCl_(3) (g) + Cl_(2) (g) ` If the three gases are mixed in a rigid container so that the partial pressure of each gas is initially 1 atm, which is true ?A. More `PCl_(5)` will be producedB. More `PCl_(3)` will be producedC. Equilibrium will be established when 50% of the reaction is completeD. None of the above |

Answer» Correct Answer - A `Q_(p) = (p_(PCl_(3))xxp_(Cl_(2)))/(p_(PCl_(5)))=(1 atm xx1 atm )/(1atm )=1` As `Q_(p) gt K_(c)` , equilibrium will go in the backward direction , i.e., more `PCl_(5)` will be produced . |
