How the prediction of reaction is carried out ? (a) By the value of K

1.	How the prediction of reaction is carried out ? (a) By the value of K (b) By the value of Q (c) By the value of DeltaG(d) By the value DeltaG^ө .
Answer» SOLUTION :(a) Value of K: By the value of K information about equilibrium can be obtained. (1) If `K_c gt 10^3`,So product is more and reaction is toward completion. (ii) If `K_c lt 10^(-3)` , So product is negligible reaction almost not take place. (iii) If `K_c = 10^3`to `10^(-3)` at equilibrium product and REACTANTS are comparable. (b) Reaction predicting and Value of `Q_c`: (1) If `Q_c ltK_c`, reaction move in forward direction. (ii) If `Q_c gt K_c`,reaction move in reverse direction. (iii) If `Q_c = K_c`,reaction is in equilibrium and will not move forward. (c) Reaction of spontaneity (Predicting) and Value of `DeltaG`: (i)`DeltaG lt 0` reaction is SPONTANEOUS. (ii) `DeltaG gt 0`reaction is non-spontaneous. (iii) `DeltaG = 0` reaction is in equilibrium. (d)`DeltaG^(ө)` and K and Reaction of spontaneity : (i) `DeltaG^(ө)lt0` means negative, So `K_cgt 1`. Reaction is spontaneity and product will be more reaction proceed in forward direction . (ii) `DeltaG^(ө) gt 0`means positive, So `K_clt 1`. Reaction is not spontaneous and product will be less. Reaction proceed in reverse direction. (iii) AGO = 0, K= 1 So, equilibrium state is attain.
