Consider the expression Delta G= - RT " In " K_(p)+RT " In " Q_(p) and select the correct statement at equilibrium where Q_(p) and K_(p) term refer to reaction quotient and eq uilibrium constant at constant pressure respectively.

Answer»

`Delta G= 0, Q_(p) GT K_(p)`the EQUILIBRIUM reaction will SHIFT from left to right
`Delta G=0, Q_(p)=K_(p)` the equilibrium reaction will shift from left to right
`Delta G= oo, Q_(p) lt K_(p)` the equilibrium reaction will shift from right to left
`DeltaG lt 0, Q_(p) gt K_(p)` the equilirbium reaction will shift from right to left

Solution :Van't Hoff reaction isothenn is `Delta G= Delta G^(@)+RT` In Qp When the reaction is in a state of equilibrium `Delta G=0` M
Then `Delta G^(@)= - RT " In " Q_(p)= - RT " In" K_(p)`
