The value of `log_(10)K` for a reaction `A hArr B` is (Given: `Delta_(f)H_(298K)^(Theta) =- 54.07 kJ mol^(-1)`,
`Delta_(r)S_(298K)^(Theta) =10 JK^(=1) mol^(-1)`, and `R = 8.314 J K^(-1) mol^(-1)`

A

`5`

B

`10`

C

`95`

D

`100`

Text Solution

Verified by Experts

`DeltaG^(@)=-2.303RT log K`
or `DeltaH^(@)-TDeltaS^(@)=-2.303Rt logK`
`[-54.07xx10^(3)-298xx10]=-2.303xx8.314xx298 log K`
`:. Log K=(57050)/(5705)=10`
