If K(c) is not numerically equal to K(p)...

If `K_(c)` is not numerically equal to `K_(p)`, how can both of the following equations be valid?
`DeltaG^(ɵ)=-2.303 RT log K_(c), DeltaG^(ɵ)=-2.303 RT log K_(p)`

Text Solution

Verified by Experts

`triangleG^(0)` will have two different values but the first equation referes to the standard state in which all reactants and products are 1M, and the second equation refers to the standard state in which all reactants and products are at 1 atm.

Entropy is a state function and its value depends on two or three variable temperature (T), Pressure(P) and volume (V). Entropy change for an ideal gas having number of moles(n) can be determined by the following equation. DeltaS=2.303 "nC"_(v)"log"((T_(2))/(T_(1))) + 2.303 "nR log" ((V_(2))/(V_(1))) DeltaS=2.303 "nC"_(P) "log"((T_(2))/(T_(1))) + 2.303 "nR log" ((P_(1))/(P_(2))) Since free energy change for a process or a chemical equation is a deciding factor of spontaneity , which can be obtained by using entropy change (DeltaS) according to the expression, DeltaG = DeltaH -TDeltaS at a temperature T What would be the entropy change involved in thermodynamic expansion of 2 moles of a gas from a volume of 5 L to a volume of 50 L at 25^(@) C [Given R=8.3 J//"mole"-K]
