Standard Cell Potential

JEE Main asked Standard Cell Potential 13 times in 13 of the 108 shifts Lumi analysed, in 2017, 2021, 2022, 2023, 2024, 2025 and 2026. It belongs to Nernst Equation, in Electrochemistry (Chemistry). The longest wait between two years asking it was 4 years, across 2018 and 2019, which Lumi has no shifts for. In 2022, 2023 and 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2017, 2021, 2022, 2023, 2024, 2025 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
