Log Base 10 Arrhenius Plot Slope

JEE Main asked Log Base 10 Arrhenius Plot Slope 4 times in 4 of the 108 shifts Lumi analysed, in 2020, 2021, 2022 and 2025. It belongs to Arrhenius Equation, in Chemical Kinetics (Chemistry). The longest wait between two years asking it was 3 years.

Questions on this idea a shift, by year

2017–2026. Asked in 2020, 2021, 2022 and 2025. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
