Predict whether the following reaction is possible or not at `300k`.
`2CuO(s) rarr Cu_(2)O(s) +1//2O_(2)(g)`
`DeltaH =- 144.6 kJ mol^(-1), DeltaS = 0.116 kJ mol^(-1)`

Text Solution

Verified by Experts

`DeltaG = DeltaH - T DeltaS`
`=- 144.6 - 300 xx 0.116 =- 179.4 kJ mol^(-1)`
`DeltaG =- ve`
`:.` reaction is spontaneous.
