Two-Point Arrhenius Equation

JEE Main asked Two-Point Arrhenius Equation 7 times in 7 of the 108 shifts Lumi analysed, in 2020, 2021, 2022 and 2026. It belongs to Arrhenius Equation, in Chemical Kinetics (Chemistry). The longest wait between two years asking it was 4 years. In 2020, 2021 and 2026 it came in more than one shift of the same year.

Questions on this idea a shift, by year

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

How JEE Main framed it

Numerical value is the usual form. Skill tested: calculation.

  • Temperature from rate constants and ea
  • Statement i/ii on rate constant and half-life
