Consider the reaction where K_(p)=0.497at 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 ?

Answer»

<P>More `PCl_(5)` will be produced
More `PCl_(3)` will be produced
Equilibrium will be established when 50% REACTION is complete
None of the above

Solution :`PCl_(5)hArr PCl_(3)+Cl_(2)`
`K_(p)=0.497`
`Q=(P_(PCl_(3))xx P_(Cl_(2)))/(P_(PCl_(5)))=(1xx1)/(1)=1`
Since `Q gt K_(p)`, the reaction will PROCEED in backward DIRECTION. Hence, more `PCl_(5)` will be produced.
