Important Electrochemistry Formulas for JEE Main 2024
With the JEE Main 2024 exams round the corner, the students must start with their revisions. Electrochemistry is a unit that comes under the Chemistry section of the JEE Mains examination. The formulas in Electrochemistry must be remembered as they are crucial to solving the numerical problems.
The most important Electrochemistry formulas for JEE Main 2024 have been listed under:
- ∆G = -nFEcell
- ∆G ֯= -nFE֯ cell
- For an electrode, Oxidation Potential = - Reduction Potential
- Ecell = RP of Cathode – RP of Anode
- Ecell = RP of Cathode + OP of Anode
- E֯cell = SRP OF Cathode – SRP of Anode
- w ∝ Q or w ∝ (I x t) w = Zit W ∝ E W/E = F (constant)
- I = V/R
- ρ = R.a/l
- K = 1/ρ
- C = 1/R
- Equivalent conductivity = Conductivity / Concentration in equivalents per unit volume
- Λm = K/Cm
- λ∞eq = λ∞c + λ∞a
- λ∞eq = Equivalent conductivity at an infinite dilution
- λ∞a = Conductivity of an anion at an infinite dilution
- λ∞c = Conductivity of a cation at an infinite dilution
- Ecell = E0 – [RT/zF]
