Chemical equilibrium is attained in a reversible reaction carried in a close container and is of dynamic nature. The value of equilibrium constant may be expressed either as `K_(p)" and " K_(c)` and the two are related to each other as : `K_(p) =K_(c)(RT)^(Deltang)` Free energy change `(DeltaG)` at equilibrium point is zero. The value of equilibrium constant gives the extent to which a particular reation has proceeded to attain the equilibrium . Its value gets reversed if the reaction is reversed and becomes the square root of the initial value if the reaction is divided by 2. A reaction attains equilibrium when the free energy change accompanying the reaction is :A. Positive and largeB. ZeroC. NegativeD. Negative and small. |
