What is the sign of Δ G ° and the value of K an electrochemical cell for which E c e l l o = 0.80 V ? Δ G ° K
Options
- AΔG = -ve k >1
- BΔG = +ve k >1
- CΔG = +ve k <1
- DΔG = -ve k <1
Correct answer
A. ΔG = -ve k >1
Step-by-step solution
As Δ G ° = - n F E c e l l o = - 0.8 n F Hence Δ G ° = negative K e q = a n t i l o g - Δ G ° 2.303 R T As Δ G ° is negative so K e q will be positive or > 1.
