Kc and Kp Relationship

JEE Main asked Kc and Kp Relationship 4 times in 4 of the 108 shifts Lumi analysed, in 2021 and 2024. It belongs to Chemical Equilibrium, in Equilibrium (Chemistry). The longest wait between two years asking it was 3 years. In 2021 and 2024 it came in more than one shift of the same year.
