Cell reaction is spontaneous when
Three cell A, B and C has equilibrium constant in the ratio 1:4 : 9 respectively. Arrange the following cells in the order of increasing Gibbs free energy.
Gibbs free energy change for a cell reaction is positive what does it indicates?
In the equation, ΔG° = – nF E° cell ; F is:
Consider the cell reaction:
Cd(s) | Cd2+ (1.0 M) || Cu2+ (1.0 m) | Cu (s)
If we wish to make a cell with more positive voltage using the same substances, we should:
. The electrode potential at any concentration measured with respect to standard hydrogen electrode can be represented by:
. For an equation: Ni(s) + 2Ag+(aq) → Ni2+ (aq) + 2Ag(s) the Nernst equation is written as:
Nernst equation for an electrode is based on the variation of electrode potential of an electrode with:
Nernst equation for an electrode is based on the variation of electrode potential of an electrode with temperature and concentration of electrolyte.
The free energy change for the following cell reaction is given as :
2Au3+ (aq) + 3Cu (s) → 2Au (s) + 3Cu2+ (aq)
