Given below are the values of DeltaH^(ɵ)...

Given below are the values of `DeltaH^(ɵ)` and `DeltaS^(ɵ)` for the reaction given below at `27^(@)C`.
`SO_(2)(g)+1/2O_(2)(g) rarr SO_(3)(g)`
`DeltaH^(ɵ)=-98.32 kJ mol^(-1), DeltaS^(ɵ)=-95 J mol^(-1)`
Find `K_(p)` for the reaction

Text Solution

Verified by Experts

`log_(10)K_p=(DeltaH^@)/(2.303RT)+(DeltaS^@)/(2.303xxR)`
`therefore log_(10)k_p=(98320)/(2.303xx8.314xx300)-(95)/(2.303xx8.314)`
`therefore K_p=1.44xx10^(12)atm ^(-1//2)`
