Calculate the standard free energy for a...

Calculate the standard free energy for a reaction `X hArr Y`, if the value of equilibrium constant is `1.8 xx 10^(-7)` at 298 K.

Text Solution

Verified by Experts

We know that `Delta G^(@) = -2.303 RT log K`
`= 2.303 xx 8.314 JK^(-1) mol^(-1) xx 298 K xx log.18 xx 10^(-7)`
`Delta G^(@) = 38.484 KJ mol^(-1)`
